Fit Notes
Athleta is cut on a slightly more generous block than Lululemon, with wider hip-to-waist ratios and softer waistbands — good news for anyone who finds Lululemon Align tight at the top. The Elation and Salutation tights are the workhorses and run true to size; the Ultra High Rise Transcend runs about half a size small in the waist and buyers with a defined hip-to-waist drop routinely size up on it. Tops in the Ultimate line are cut athletic-slim, not oversized, despite the branding, and the Conscious Crop tee runs a full length shorter than a standard tee. Petite and Tall lines are separately drafted rather than scaled.
Common Sizing Mistakes
The main mistake is treating Athleta as a straight swap for Lululemon and ordering the same numeric size — Athleta typically runs half a size more generous, and the Elation tight in a Lululemon Align size will sit loose at the waist. The second, on plus and petite lines, is not realizing they use their own separately drafted blocks rather than just being scaled versions of the core size chart. A third issue is swimwear: the Kata one-piece and the Aqualuxe pieces use different chest coverage, so cross-shopping within Athleta swim isn't always predictable.
How Athleta Compares
Against Lululemon, Athleta feels softer through the waistband and slightly less compressive at the same size, which is the trade-off buyers make when they migrate. Against Gap (its parent), Athleta apparel is more athletic in cut and much more consistent — Athleta's size medium doesn't drift the way Gap's fashion-line medium sometimes does. Against Vuori, Athleta women's is comparable in waistband softness but a touch shorter in the inseam at the same nominal size.
