How To Choose Plus-Size Fitness Clothing Brands: 15+ Best Brands

Finding fitness clothing that fits, supports, and moves with your body shouldn't be this hard. Yet for plus-size athletes, it often is.

Inclusive fitness apparel has improved a lot from the limited, unflattering options of the past. But too many brands claim to offer "extended sizes" and fall short. Some brands stop at 2X and call it inclusive. Others offer larger sizes but skip the technical features that make activewear work during a HIIT class or long run.

We've done the research for you. We tested over 15 brands that truly understand workout gear for curves. You'll find moisture-wicking plus size leggings that won't roll down mid-burpee. You'll find supportive plus size sports bras designed by people who know what real support means.

Looking for affordable finds? Or investment pieces that'll last years? Need plus size yoga pants with pockets? Or breathable plus size gym wear for hot yoga? This guide helps you choose plus-size fitness clothing brands worth your money and trust.

1. Girlfriend Collective (XXS-6XL) - Best for Sustainability & High-Impact Support

Girlfriend Collective proves eco-friendly gear can still perform. Their compressive leggings and high-impact sports bras handle tough workouts—HIIT sessions, trail runs, you name it.

Size Range : XXS to 6XL (US 0-32), with extended sizing across bras, leggings, shorts, and tops.

Why They Stand Out for Plus-Size Athletes :

The fabric blend (79% recycled polyester + 21% spandex) gives you serious support. Comfort stays intact. Each sports bra repurposes about 11 post-consumer plastic bottles . Each pair of leggings diverts around 25 bottles from landfills and oceans. High-impact styles like the Paloma, Dylan, and Tommy bras come with wide bands and high necklines. These features cut down bounce during intense cardio.

Sustainability That Matters :

Girlfriend Collective runs a ReGirlfriend take-back program . Return your worn Compressive leggings. They'll upcycle them into new garments. Their Vietnam factory holds SA8000 certification for ethical labor. All fabrics are OEKO-TEX certified for chemical safety. They even clean dye wastewater on-site. Residual sludge gets recycled into pavement materials.

Good On You rates them "Good" overall. A solid pick for those who value ethics and performance the same.

2. Fabletics (Up to 3X) - Best Value for Money

Fabletics turns membership into real savings. The VIP program costs $59.95 per month . Here's the brilliant part: that fee becomes a credit worth items up to $100 . You triple your spending power with each charge.

Size Range : XS to 3X across leggings, sports bras, tops, and outfits designed for movement.

The Membership Math That Works :

Skip any month between the 1st and 5th without penalty. You keep all VIP perks— up to 50% off retail prices on new drops, 20-50% off full-priced styles, and exclusive sales for members only. Non-members pay full retail. VIPs get the same quality for half the cost.

Loyalty Rewards Built In :

The points system rewards repeat purchases. Gold members (under 3 months) earn 1 point per dollar spent . Platinum members (over 3 months) double that to 2 points per dollar . Write a product review? Add 20 points . Redeem 1,000 points for $10 off . Save 2,000 points for a free outfit . Points expire after 12 months. Regular shoppers benefit most.

Beyond the Basics :

Free shipping kicks in at $49 . Returns stay hassle-free for 45 days . VIPs unlock the Fabletics FIT app with on-demand workout classes. You also get first access to celebrity collaborations. New collections drop for members first—sometimes weeks before public release.

The value works best for those who shop once or twice a month. Occasional buyers might find the membership fee harder to justify.

3. Lane Bryant LIVI Collection (10/12-38/40) - Best High-Waist No-Roll Design

The waistband changes everything. Lane Bryant's LIVI Collection built a 4-inch waistband that stays put. No mid-squat adjustments. No constant tugging between sets.

Size Range : 10/12 to 38/40 across leggings, capris, and 7/8 lengths built for real movement.

The No-Roll Promise That Delivers :

The 2-inch covered elastic waistband sits wider than standard activewear. This spreads pressure across your midsection. It won't dig into one spot. The fabric lays flat against skin. During burpees or mountain climbers, it moves with your body. Customer FerrettiA confirms: " No waist slipping. No rolling down. No losing shape. " Those three things matter more than any trend.

Inseam Options for Every Height :

Short inseam offers 26 inches in full-length styles. Regular extends to 25.5 inches for 7/8 cuts and 28 inches for full. Long reaches 28.5 inches (7/8) or 31 inches (full). You get the right length for your height. No bunching at the ankle. No riding too high.

Fabric Choices Worth Knowing :

LIVI Soft gives you that buttery-soft hand feel. Wicking fabric pulls moisture away during hot yoga or treadmill runs. Signature Stretch blends cotton for breathability with slimming mesh panels in key areas. Recycled LIVI diverts plastic from landfills and delivers the same compression. Pick based on your workout intensity and climate needs.

4. Old Navy (XS-4X) - Best Budget-Friendly Extended Sizing

Old Navy made history in August 2021 with their BODEQUALITY initiative. Same price across all sizes, from XS to 4X. No plus-size upcharges. Ever. Extended sizes cost 10-20% more at most activewear brands. Old Navy doesn't do that.

Size Range : XS to 4X (US 0-30) online, with 0-28 available in over 1,200 stores nationwide.

Why Price Equality Matters :

Most brands charge extra for fabric. They say it costs more to produce. Old Navy removed that barrier. A pair of plus size leggings for working out costs the same as size small. This pricing model opened doors for millions. These shoppers had been priced out before.

The Fit That Earned Trust :

TrueFit surveyed 89 million members in 2022. Old Navy ranked as the #1 favorite fitting brand in America. They beat Nike, American Eagle, and even parent company Gap. A budget retailer outranked premium athletic brands. That tells you something about their sizing accuracy. The fit stays consistent across the range.

What Changed (And Why) :

Old Navy rolled out extended sizing too fast in 2022. Excess inventory piled up. Markdowns followed and hurt profits. They pulled back in-store stock at 75 U.S. and 15 Canadian locations. But here's what stayed: over 90% of stores still carry extended sizes. They stock based on local demand. The full XS-4X range lives online with free shipping over $50.

The Bigger Picture :

70% of U.S. women wear extended sizes. The plus-size market hit $324.23 billion in 2025 . Old Navy placed itself right at the center of accessibility and growth. They aimed for $10 billion in sales by 2023 (up from $7.5 billion in 2020). Inclusive sizing drove that goal as a core strategy. Not an afterthought.

Budget-conscious shoppers want breathable plus size gym wear without the high price. Old Navy gives you functional basics. Quality doesn't take a back seat to cost.

5. Nike (Up to 3X/Size 24) - Best for Running & High-Visibility Colors

Nike's running line goes up to size 18 men's (about equal to 3X/Size 24 in extended fits). Women's sizes run from 5-12. The real draw? Bold, bright colors that keep you safe during early-morning or evening runs.

The Visibility Advantage :

Nike ranks 36 top reflective models for 2025. But color does the work before reflective parts even matter. The Vomero 18 pairs a clean white upper with green accents and a bright green midsole . Drivers spot you blocks away. The Zoom 6 comes in 7 color options . Bold orange with neon accents is one. The 3 goes further with bright crimson red and lime blast accents . These aren't subtle trainer colors. They're built for visibility.

Performance That Backs the Look :

Nike's ZoomX foam delivers 74.8% energy return in race shoes. That beats the 73.4% average . The Vomero 18 is Nike's most cushioned running shoe at 11.5 oz (men) and 9.3 oz (women) . Stack height measures 46–36 mm . The 3 drops to 7.8 oz (men) for race day. It has 40% softer ZoomX foam and 77.9% forefoot energy return . Shock absorption hits 147-155 SA . That's 21.1% above average . Your joints feel that difference mile after mile.

Strava data shows the Pegasus outsells Hoka among serious runners. Nike earned trust through consistent performance. Marketing didn't build that alone.

6. Lululemon (14-20/XXL+) - Best Premium Quality & Stretch

Lululemon's technical fabrics earned their cult following through performance, not hype. Their Nulu™ and Everlux™ materials give you four-way stretch. They move with your body during downward dog or deadlifts. You get durability that pays off—these pieces last years, not months.

Size Range : 14 to 20 (XXL to 2X), with specific measurements that match real bodies.

The Sizing That Makes Sense :

Size 14 fits a 42" bust, 35" waist, and 45" hip . Size 16 accommodates 44-45" bust, 38-39" waist, 47" hip . Size 18 measures 46-47" bust, 41" waist, 49" hip . Size 20 reaches 48-51" bust, 43" waist, 51" hip . Standard inseams run 32 inches . Tall options extend to 35 inches for size 16 and 34¾ inches for sizes 18-20.

What You'll Find in Extended Sizes :

Stretchy tanks layer well under hoodies. Workout tights use ultra-fast-drying fabric that wicks moisture in seconds. Yoga gear includes the beloved Align collection. Hoodies add warmth without bulk. The fabric stays strong wash after wash. No sagging. No pilling. No lost compression.

7. Athleta (XS-4X) - Best for Versatility & Swim Options

Athleta doesn't make you pick between activewear and swimwear. Their collection does both. And does them well.

Size Range : XXS to 3X (US 00-26), with letter sizes XS through 3X covering the full range. Size 3X fits a 44.5-46" waist and 55.5-58" hip . Size 2X fits 40-42" waist and 51-53" hip . That's real room for curves.

The Swim Versatility That Sets Them Apart :

You get bra-cup sizing from B to DD . Not those generic S/M/L swim tops that never work right. The Seabreeze crop tankini offers D-DD cup support . Underwire styles add structure where you need it. Molded cups and built-in shelf bras take out the guesswork. Bottom coverage runs from cheeky to high-waist hipster. Their Surge shorts work for both swim and sport. Great for paddleboarding or beach volleyball.

Performance Worth Knowing :

Every piece uses 100% recycled materials . The fabric has LYCRA XTRA LIFE spandex . This lasts 5-10× longer than standard swimwear. These pieces handle chlorine, salt water, and sun season after season. They keep their shape. They don't fade.

The Price-to-Value Ratio :

List prices hit $49-$69 for bikini tops and tankinis. Sales drop them to $19.97-$29.97 . The Sun Shield rashguard one-piece lists at $119 . It often drops to $34.97 . High-waist and hipster bottoms retail at $55 . They go on sale for $14.97 often. Wait for promotions and stock up.

8. Torrid (0X-4X+/Size 10-30) - Best One-Stop Plus-Size Shop

Torrid built its entire business around one simple truth: plus-size women deserve fashion-forward activewear without compromise. Their 560 stores across the U.S. carry everything from supportive plus size sports bras to flexible plus size fitness apparel . All pieces fit sizes 0X to 4X+ (10-30) .

Why It's Your Complete Shopping Solution :

You won't find token "extended sizes" tucked in a back corner. Torrid stocks tops, bottoms, dresses, intimates, activewear, footwear, and accessories. Every piece is cut for curves. Their activewear line gives you moisture-wicking plus size clothing with the same features as straight-size brands. High-waist leggings stay put during burpees. Sports bras offer real support built for D+ cups.

The Numbers Tell a Harder Story :

Torrid closed 74 stores through Q3 2025. They plan about 100 more closures by fiscal year-end. Q3 sales dropped to $235.2 million —down 10.8% from the prior year's $263.8 million . Comparable sales fell 8% . The company posted a $6.4 million net loss versus $1.2 million the year before.

But here's what stayed strong: gross profit margin held at 34.9% . Revenue still hit $390.1 million with $23.3 million profit . Torrid's shifting toward digital sales and outdoor shopping centers. They're betting on sub-brands and fresh ideas to rebuild momentum.

Sustainability Enters the Picture :

Torrid launched a collection using recycled polyester and nylon . Green materials now appear across select activewear pieces. It's a start—not a full change, but progress matters.

The brand remains a go-to for curve-focused workout gear shoppers who want options beyond basic black leggings.

9. ASOS Curve (0X-4X/Size 12-30) - Best for Bold Prints & International Shipping

ASOS Curve offers 3,650+ styles full of color, pattern, and global reach. Their plus-size collection makes a statement. Think rust florals, blue plaids, and burgundy satins that put boring basics to shame.

Size Range : US 12 to 30 (about 0X to 4X). Each product page has brand-specific size guides . Shopping from abroad? You get conversion charts for UK, EU, and other regions right in the interface.

The Print Selection That Stands Out :

The crinkle pleated blouson sleeve maxi mixes red and blue florals for $59.99 . These are bold, saturated colors—not timid pastels. The crinkle chiffon gathered maxi features a rust floral print with micro ruffles . It started at $149 but drops to $104.50 on sale. A washed gray and blue plaid mini shirt dress has godets for easy movement. The nipped-in waist gives you shape. These prints aren't trend fillers. They define the whole look.

The Fit Assistant Tool :

Enter your height, age, weight , and past order history . A blue icon appears near size dropdowns. It suggests your best fit for each Curve piece. The tool accounts for brand differences and fabric stretch. No more size guesswork.

Why International Shipping Matters Here :

ASOS ships to over 200 countries . The US site has tools for global shoppers looking for supportive plus size activewear or flexible plus size fitness apparel . Size charts convert easily. Returns work across borders without hassle. Shopping from outside the U.S. for breathable plus size gym wear ? ASOS removes barriers other brands leave in place.

10. Halara (XS-4X) - Best for Athleisure & Tennis-Inspired Styles

Halara brings tennis-court style to your daily workouts. Their athleisure pieces work for both gym sessions and casual wear. You get flexible plus size fitness apparel that goes from morning yoga to afternoon errands. No outfit change needed.

Size Range : XS to 4X (58W/60W), with consistent sizing across their signature styles.

The Sizing Process That Removes Guesswork :

Each product page has a detailed size chart . Measure your bust, waist, and hips in inches or centimeters. Match those numbers to the XS-4X range. The Model Stats section shows you what size the model wears. You also see her height and measurements. A 6'0" customer at 230 lbs found size 1X fit true to size with perfect length. No hemming needed.

Styles Worth Your Attention :

The UltraSculpt™ High Waisted Tummy Control Pocket Shaping leggings run from XXS through 4X. You get compression where it counts. No squeezed feeling. The High Waisted Crossover Full Length Flare Plus Size Leggings add vintage tennis vibes with a modern look. Halara's Flex™ High Waisted Pocket Wide Leg Waffle Work pants give you high-waist support. The textured fabric looks polished outside the gym too.

These pieces work because they get it. Real bodies need real pockets and real support—not just cute details.

11. Eloquii (14-32) - Best for Work-to-Workout Transition

Eloquii fills a gap most activewear brands miss: the time between your desk and your evening spin class. Their pieces work for both. You won't look out of place at the office or the gym.

Size Range : US 14 to 32, with split sizing (14/16, 18/20, 22/24, 26/28, 30/32) and individual numeric sizes across the full range.

The Measurements That Matter :

Natural waist measurements span 37 inches (size 14) to 63 inches (size 32) . Hip measurements run 47 inches (size 14) through 73 inches (size 32) . Bust sizing reaches 47 inches at 18/20 and expands to 69 inches at size 32 . These aren't vanity numbers. They're real measurements for real bodies.

Work-Ready Pieces That Move :

Ponte suit pants give you boardroom polish with hidden stretch. Tailored ankle pants have enough flex for biking to the office. Wide-leg and flare cuts hide your sneakers during the commute. Faux-leather and coated styles go from client meetings to happy hour. They don't look too sporty. Work-to-weekend joggers do double duty. You can wear them on casual Fridays. They're also comfy enough for your yoga mat.

International Sizing Conversions :

US size 14 converts to UK/AU 18 and EU 46 . US 20 translates to UK/AU 25 and EU 52 . US 28 matches UK/AU 32 and EU 60 . US 32 equals UK/AU 36 and EU 64 . Shopping from other countries? These direct matches make it easy.

12. Good American (00-32) - Best Athleisure-Denim Hybrids

Good American found the sweet spot between real denim and stretch-legging comfort. Their Always Fits system gives 100% stretch with four-way recovery. One pair fits your body across four numerical sizes . No midday waistband fights. No guessing if last month's jeans still work.

The "One Size Fits Four" Revolution :

Five bracket sizes cover the full 00-32 range . Size A spans 00-4 . Size B fits 6-12 . Size C works for 14-18 . Two more brackets finish the range through size 32 . Each jean stretches and bounces back. No sagging. The gap-proof waistband grips like your favorite leggings. The shape looks like classic denim.

Performance Specs That Deliver :

The Good Legs Skinny has a 10.5" front rise and 15" back rise in the 6-12 bracket. The 29" inseam lands right at your ankle. Leg opening sits at 10" for a true skinny fit. Fabric mixes 87.5% cotton with 5% recycled cotton, 4% elasterel-P , and 3.5% elastane . You get big four-way stretch without that fake feel of regular workout pants.

The Good Legs Straight crop version has a 27.5" inseam with a 14.5" leg opening . Great for sneakers or slip-ons. Works for errands and evening plans.

13. Popflex (XXS-3X) - Best for Gym-to-Brunch Athleisure

Popflex makes activewear that doesn't look like workout clothes. You can go from morning HIIT to afternoon coffee dates. No wardrobe change needed. The brand offers XXS (00-0) through 3X (22-24) . You get three different fit systems. Pick your compression level.

The Triple-Fit System Explained :

Seamless Sculpt Fit gives you maximum compression. Size 3X fits a 51-55" bust, 46-50" waist, and 56-60" hip . Size 2X fits 47-51" bust, 42-46" waist, 52-56" hip . Everything stays in place during box jumps. Mountain climbers too.

Seamless Comfort Fit uses fun names that make sense. "Extra curveflex" covers 1X-3X. "Curveflex" handles L-XL. Measurements match Sculpt Fit. But you get gentler compression. Great for yoga or casual wear.

Standard Fit sits between the two. You get structure. No squeezed feeling. The crisscross waistband creates an hourglass shape. Supersculpt bottoms shape your body. Cargo styles have drawstring waistbands. They won't roll down.

Measurements in Metric (for international shoppers): Size 3X is 130-140 cm bust, 117-127 cm waist, 142-152 cm hip . Size 1X is 109-119 cm bust, 96-107 cm waist, 122-132 cm hip .

Measure at the fullest part of your chest. Find your narrowest waist point. Measure your widest hip area parallel to the ground. Match those numbers to the fit system that works for your day.

14. SKIMS (XXS-4X) - Best Supportive Athleisure Basics

SKIMS built its reputation on shapewear that works. Their athleisure line brings that same engineering to everyday movement. You get second-skin compression without the squeezed feeling.

Size Range : XXS to 4X (US 00-28), with precise measurements that take the guesswork out of online shopping.

The Sizing Breakdown That Matters :

Size XXS (00) fits a 31-34" bust, 23-24" waist, and 31-34" hip . Size 2X (18-20) accommodates 47-50" bust, 38-41" waist, and 49-52" hip . Size 4X (26-28) reaches 53.5-55.5" bust, 44.5-47" waist, and 55.5-57.5" hip . All measurements stay the same across their Fits Everybody collection, NikeSKIMS collaboration, and core loungewear.

Where SKIMS Stands Out :

The Fits Everybody scoopneck and turtleneck styles give you cropped lengths with 20-24" torso coverage . Size down if you have a shorter torso or want more compression. The fabric stretches enough to move. But it holds its shape wash after wash. Sports bras cover the full XXS-4X range. They give you compressive support built for low-to-medium impact workouts.

SKIMS isn't flashy. It's reliable basics that perform as promised.

15. TomboyX (XS-4X+) - Best Sustainable Underwear & Active Basics

TomboyX has its B Corp certification . This proves sustainability and inclusivity work together. Their basics fit everyone. Most styles range XS to 4X . Some underwear goes from 3XS to 6X . That's real size range.

The Sustainability Standards That Count :

Workers earn a living wage . No sweatshops here. Cotton items blend 95% OEKO-TEX certified cotton with 5% spandex . This mix is chemical-safe. Plus, it breathes well. The Tucking Bikini uses 100% recycled polyester for the body fabric. The mesh lining has 84% nylon with 16% spandex . All spandex is latex-free . Good news for sensitive skin.

What You'll Wear :

4.5" trunks start at $13 per pair . MicroModal boyshorts cost $25 . You get buttery-soft comfort. Leak-proof styles work for periods or incontinence. No bulk. Compression tops (XS-4X) layer thin. They shape your chest. Soft bras and bralettes (XS-6X) fit up to G cup . This depends on density. The 9" boxer briefs hit mid-thigh. Perfect if you hate chafing on long walks or bike rides.

Measure your chest at the widest point. Skip compression garments for this. Between sizes? Go bigger for bottoms. Underwear should lay flat. It should never dig in.

16. Berlook (0-34) - Best Sustainable Swim & Athleisure

Berlook turned 2.9 million plastic bottles into swimwear and athleisure that performs. Their sustainability numbers aren't marketing fluff. They're real impact you can wear.

Size Range : 0 to 34. This covers swimsuits, activewear, coverups, and everyday athleisure.

The Recycled Materials That Matter :

80% of their entire catalog uses sustainable fabric. The Black Floral Cutout One Piece has a shell of 94% recycled polyamide + 6% spandex . The lining uses 93% recycled polyester + 7% spandex . Their ECONYL® collection uses 100% regenerated nylon . This comes from fishing nets and fabric waste pulled from oceans and landfills.

Every fabric blend includes 10-20% spandex for stretch and recovery. These pieces resist chlorine and salt water. They hold their shape after repeated washing. Quick-drying fabric keeps you comfortable from pool to next activity.

Features Built for Real Use :

Most swimsuits come fully lined . You get adjustable straps and removable padding . Customize the fit and support to your needs. Customer measurements confirm true-to-size accuracy . A size S fits an 88 cm bust, 66 cm waist, and 91 cm hip . No size gambling here.

The Full Sustainability Picture :

Berlook uses GRS-certified recycled materials across their line. Small-batch production cuts waste. 100% compostable packaging bags replace plastic mailers. Some orders arrive in reusable linen bags made from fabric scraps. They participate in Stripe Climate to fund carbon removal projects.

Independent reviews rate them 8/10 for ethics and performance combined. Competitive pricing doesn't mean cutting corners on worker welfare or environmental standards.

How to Measure Yourself for Plus-Size Activewear: Accurate Sizing Guide

Size labels lie. Every plus-size shopper knows this truth.

A 1X at Nike fits nothing like a 1X at Under Armour. Major activewear brands show an 8-inch difference in bust measurements for the same 16W-18W size. This isn't a small gap. This means the difference between a sports bra that supports you and one that cuts into your skin or gapes at the sides.

About 67-68% of U.S. women wear size 14 and up . The activewear industry can't agree on what those sizes mean. The ASTM standard defines plus-size starting at size 16 with a 43" bust, 39" waist, and 44" hip . Walk into any store and you'll see those numbers shift brand by brand.

Nike's core XXL (20-22) and their plus 1X (16W-18W) have almost the same measurements. The bust ranges overlap by 4 inches . Hip measurements are almost identical. You could fit either category depending on which size chart you check first.

A study of 65 women who all wore size 18W showed the real problem. Their bust measurements ranged from 33.46" to 63.46" . The average was 45.83" . But that average means nothing with a 30-inch wide range. Waist and hip measurements showed the same chaos. Bodies are different. Size charts pretend they're not.

The solution? Stop trusting labels. Measure your body.

The Three Essential Measurements

You need three core numbers before you shop for activewear:

1. Full Bust Circumference

Wrap a soft measuring tape around the fullest part of your bust. Keep the tape parallel to the floor. Don't pull it tight. It should lie flat against your skin without digging in. Breathe. Write down this number in inches.

For sports bras, you'll also need your underbust measurement . Measure under your breasts where the band sits. This gives you your band size. The difference between your full bust and underbust gives you your cup size.

2. Natural Waist

Find the narrowest part of your torso. This sits an inch or two above your navel. Bend to one side. Where your body creases is your natural waist. Measure around this point. Keep the tape snug but not tight. You should slip one finger underneath easily.

High-waisted leggings need this measurement to stay in place during burpees. The waistband sits below your natural waist? It will roll down. Every time.

3. Full Hip

Stand with your feet together. Measure around the fullest part of your hips and bottom. This is 7-9 inches below your natural waist. Keep the tape parallel to the ground. Make sure it passes over the widest point of your glutes.

This measurement tells you whether leggings will stay up or slide down during squats. It affects how shorts fit your thighs. This matters for comfort.

Why These Numbers Matter More Than Size Labels

Brands use these three measurements in different ways. Some create vanity sizing. Others stick closer to industry standards. The plus-size sportswear market is growing at 7.61% annually . Brands are rushing to capture that $315.27 billion market . They're not standardizing their sizing to do it.

Compare your measurements to each brand's size chart before you buy. Don't assume your usual size will work. A 1X that fits at Old Navy might be too small at Lululemon. The numbers don't lie. The labels do.

Measure yourself every 3-6 months . Bodies change. You might start a new workout routine and your measurements shift. They change with the seasons or life events. Keep your numbers current. This saves you from ordering the wrong size and dealing with returns.

Use a flexible fabric measuring tape . The kind tailors use. Not a metal one from your toolbox. Measure in the morning before eating for consistency. Wear the undergarments you'll wear with your activewear. A sports bra changes your bust measurement. Shapewear changes your waist and hip numbers compared to regular underwear.

Write everything down. Keep a note in your phone with your current measurements and the date. Find a brand that fits well? Note which size worked and your measurements at that time. Build your own sizing reference guide. It's more reliable than any brand's chart.
