Old Navy to Athleta leggings size

The short answer

Old Navy XL is Athleta 1X by the two brands' own charts. 3 of 10 Old Navy sizes land on a different label at Athleta.

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

Every Old Navy size read across to Athleta. Letter sizes on the left, Letter on the right.
