Lululemon to Gap size

The short answer

lululemon L is Gap M or L by the two brands' own charts. 6 of 9 lululemon sizes land on a different label at Gap.

Both brands publish the body chest each size is cut for, so every row matches a chest, not a letter.

Every lululemon size read across to Gap. Letter sizes on the left, Letter on the right.

Tinted rows change label or sit between two sizes. Read from the two charts only; no formula and no averaging.

What wearers say

Charts describe a garment, not a fit. We do not collect fit reports for this category yet, so this table is the two brands' own claims and nothing more.
