Uniqlo to lululemon clothing size

The short answer

Uniqlo XS is lululemon XXS by the two brands' own charts. 7 of 7 Uniqlo sizes land on a different label at lululemon.

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

Every Uniqlo Japan sizing size read across to lululemon. 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.
