Halara to Uniqlo leggings size

The short answer

Halara XXS is Uniqlo XS by the two brands' own charts. 3 of 6 Halara sizes land on a different label at Uniqlo.

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

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