Bo+Tee to Lorna Jane leggings size

The short answer

Bo+Tee XS is Lorna Jane XXS by the two brands' own charts. 4 of 5 Bo+Tee sizes land on a different label at Lorna Jane.

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

Every Bo+Tee size read across to Lorna Jane. Letter sizes on the left, Letter on the right.
