Plus-size activewear has historically meant scaled-up patterns that bunch, roll, or lose compression in the wrong places, but several mainstream brands have finally invested in true extended-size patterning rather than simply grading up a straight-size cut. This guide covers five brands and price ranges between $20 and $90 for leggings, sports bras, and athleisure sets built specifically with plus-size fit in mind. Sizing still varies meaningfully between these brands, so checking each one’s specific size chart before ordering is worth the extra step even within a brand you already know.
1. Old Navy PowerSoft Plus-Size Leggings — best budget everyday legging
Old Navy’s PowerSoft line extends its popular squat-proof, non-see-through leggings all the way through extended plus sizes, and the brand has specifically re-patterned the plus range rather than just scaling up the straight-size block, which shows in how the fabric sits at the waistband and inseam. The price point makes it realistic to own several pairs in rotation for both workouts and everyday wear. It’s a dependable, low-cost entry point for building out an activewear rotation. Expect $25-$35 per pair, often less during sales.
2. Athleta Plus-Size Collection — best for higher-performance workouts
Athleta extends most of its core lines into plus sizes rather than offering a separate, more limited plus collection, which means the same compression, moisture-wicking, and support features found in its straight-size activewear carry through. The brand’s sports bras in particular get consistent praise for actual support during higher-impact workouts, a category plus-size shoppers often struggle to find well-fitted options in. It’s a stronger pick for anyone doing regular cardio or strength training rather than casual wear. Budget $50-$80.
3. Torrid Activewear — best for a plus-size-first fit philosophy
Torrid designs its entire catalog around plus and extended sizing rather than adding it as an afterthought, and that shows specifically in how its activewear handles proportions — rise, thigh room, and bra band sizing — that straight-size-first brands often get wrong when they scale up. The brand also offers a wider size range at the upper end than most mainstream activewear lines reach. It’s worth checking first for anyone who has struggled to find true plus-size activewear fit elsewhere. Expect $30-$55.
4. Fabletics Plus-Size Sets — best for coordinated athleisure sets
Fabletics’ membership-model pricing means matching legging-and-top sets can come in noticeably cheaper per piece than buying similar quality separately elsewhere, and the brand’s plus-size range covers both leggings and sports bras with consistent sizing across styles. The coordinated sets make it easy to build a full athleisure wardrobe quickly rather than piecing it together from different brands with inconsistent fits. It’s a good pick for anyone who wants matching sets without hunting for coordinating pieces separately. Budget $40-$70 per set outside membership pricing.
5. Nike Plus-Size Leggings and Sports Bras — best for brand-name performance fabric
Nike’s plus-size line uses the same Dri-FIT technology and compression engineering found in its straight-size activewear, which matters for anyone specifically shopping for performance features like sweat-wicking and four-way stretch rather than casual comfort alone. The brand’s plus-size sports bra range in particular has expanded significantly in recent years to cover higher-support styles suited to running and higher-impact training. It’s a pricier pick but one built on proven athletic fabric technology. Expect $45-$90.
How to get the best price
- Shop January and September specifically, when most retailers run their biggest activewear promotions tied to New Year and back-to-fitness marketing pushes.
- Sign up for brand loyalty programs like Nike Membership or Old Navy’s rewards, which frequently unlock early access to sales and member-only discount codes.
- Compare a coordinated set’s per-piece price against buying the same pieces separately, since bundled sets don’t always work out cheaper despite how they’re marketed.
- Check each brand’s own clearance or “last chance” section before checking third-party retailers, since plus-size activewear tends to sell out fast at full price and land in clearance quickly after.
The gap between well-fitted and poorly-fitted plus-size activewear usually comes down to whether a brand actually re-patterned its plus range or just scaled up a straight-size block, and the five brands above have consistently invested in the former. Trying a size in both a legging and a sports bra from a new-to-you brand before committing to a full wardrobe swap is worth the extra step given how much fit varies between them, and reading recent customer reviews for feedback on stretch and longevity can help narrow the choice further before buying multiples.
