Uniqlo to Halara leggings size

The short answer

Uniqlo XS is Halara XXS by the two brands' own charts. 5 of 7 Uniqlo sizes land on a different label at Halara.

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

Every Uniqlo size read across to Halara UltraSculpt. Letter sizes on the left, Letter on the right.
