Lululemon Size Chart
Activewear · women's
Lululemon uses a numeric sizing system from 0 to 20, with an accompanying letter mapping where a 6 is Small, 8 is Medium, and 10 is Large. A size 8 corresponds to roughly a 91.5cm bust, 73.5cm waist, and 99cm hip. Lululemon's pieces are engineered for a close, supportive fit, so even when a garment matches the size chart it can feel smaller than you expect. The key fit rule is category-dependent: Align leggings run true to size and feel forgiving, while Wunder Train leggings and every sports bra run small — most people size up in those. Lululemon publishes its chart in inches rather than centimetres, and fit can shift slightly when fabrics are updated season to season. Buying Lululemon secondhand is popular because the construction lasts; just confirm the exact style name in the listing, since fit varies more by style than by size.

A Lululemon size 8 maps to Medium and corresponds to roughly a 91.5cm bust, 73.5cm waist and 99cm hip. These centimetre figures are converted from Lululemon's official inch chart, as the brand does not publish centimetres.
