Plus-size activewear has improved dramatically — Girlfriend Collective and Beyond Yoga extended lines prove demand. But inclusive alpha sizing still grades one pattern: waist roll-down, thigh squeeze, and camel-toe issues persist when proportions don't match the block. This guide covers the best ready-to-wear options and when custom fit wins.
Widest ready-to-wear ranges
Girlfriend Collective: XXS–6XL — compressive, high waist.
Beyond Yoga: 1X–4X Spacedye — soft hand, free US returns.
Athleta: 3XL with length options — Powervita Salutation line.
Compare Outdoor Voices vs Girlfriend vs Knot.
Common fit failures
Waist roll-down: rise too low or waistband too narrow for midsection.
Thigh squeeze at correct waist: size up loosens waist — pattern issue.

Custom alternative
Made-to-measure doesn't 'extend' a block — it drafts for your measurements at any size.
