Year of Ours to Spanx leggings size

The short answer

Year of Ours Extra Small is Spanx XS by the two brands' own charts. 5 of 6 Year of Ours sizes land on a different label at Spanx.

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

Every Year of Ours size read across to Spanx. Letter sizes on the left, Letter on the right.
