# Size-Inclusive Activewear FORM Expanded Its Range to Embrace Every Body Type By Grace Mahas | Published 2026-04-13 | Fashion Source: Trend Hunter, https://www.trendhunter.com/trends/form-activewear References: [instagram](https://www.instagram.com/ellahalikas/) & [joinform](https://joinform.com/collections/shopform)  Beloved activewear brand [FORM](https://www.trendhunter.com/trends/90sinspired-activewear) recently launched a new collection that marks a meaningful shift in how it approaches fit. Rather than treating [extended sizing](https://www.trendhunter.com/trends/curve-by-the-shirt-company) (XS–XXXL) as an afterthought, the brand rebuilt its entire fit architecture from the ground up, ensuring that fabrics, support, and the signature sculpting feel remain consistent across all sizes. This isn't a separate line—it's a fundamental expansion that will carry forward across every future release. The collection reissues FORM's bestsellers—camis, core shorts, core leggings, and its cult-favorite layered bra—in fresh blue and grey colorways. Each piece was engineered with the same [premium construction](https://www.trendhunter.com/trends/set-active-unveils-luxform) and attention to detail, signaling that inclusivity here is structural, not performative. By making its most-loved silhouettes accessible across a wider range of bodies, FORM is acknowledging a simple truth: great activewear shouldn't be limited by size. ## Trend Insights (Trend Hunter) - Score: 3.6/10 - Popularity: 22% | Activity: 14% | Freshness: 72% - Audience gender: 10% men, 90% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Fashion](https://www.trendhunter.com/fashion) ## Key Themes ### Why This Trend Is Growing - **Size-inclusive Fit Engineering:** Ground-up fit architecture that preserves performance and sculpting across XS–XXXL, redefining expectations for parity in garment behavior. - **Unified Product Architecture:** A single-line approach where inclusivity is embedded into core designs rather than segregated into separate collections, shifting brand and production models. - **Premium Construction for All Sizes:** Consistent use of high-quality fabrics and support systems across the full size range, challenging cost-quality trade-offs in extended sizing. ### Industries Being Reshaped - **Apparel Manufacturing:** Manufacturing processes that accommodate variable grading and patterning at scale, enabling consistent fit and finish across expanded size ranges. - **Sportswear Retail:** Retail assortments and merchandising strategies adapting to unified-size lines, influencing inventory planning and customer experience expectations. - **Textile Materials R&D:** Material innovation focused on stretch, recovery, and support performance across diverse body shapes, prompting new testing and development criteria. ## Related on Trend Hunter - [Jumbo Sun Sticks](https://www.trendhunter.com/trends/ultra-sun-protector-clear-stick-spf-50.md) - [Post-Workout Shower Jellies](https://www.trendhunter.com/trends/the-good-hour-shower-jelly.md) - [Workout Hair Masks](https://www.trendhunter.com/trends/hairgym.md) - [Cosmetic Fitness Club Partnerships](https://www.trendhunter.com/trends/equinox-and-le-labo.md) - [FDA-Cleared Antimicrobial Purifying Mists](https://www.trendhunter.com/trends/antimicrobial-purifying-mist.md) - [At-Home Facial Sculpting Devices](https://www.trendhunter.com/trends/facegym-pro.md) - [Soothing Skincare Partnerships](https://www.trendhunter.com/trends/tower-28-and-pvolve.md) - [All-Natural Performance Skincare](https://www.trendhunter.com/trends/hodos-labs.md) - [Elevated Classic Sneaker Silhouettes](https://www.trendhunter.com/trends/classic-sneakers.md)
