2XU to Lorna Jane leggings size

The short answer

2XU XS is Lorna Jane XXS by the two brands' own charts. 5 of 5 2XU 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 2XU Flex & Fluid Tights size read across to Lorna Jane. Letter sizes on the left, Letter on the right.
