Spanx to Oysho leggings size

The short answer

Spanx S is Oysho M by the two brands' own charts. 4 of 7 Spanx sizes land on a different label at Oysho.

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

Every Spanx size read across to Oysho. Letter sizes on the left, Letter on the right.
