Tory Burch to Athleta clothing size

The short answer

Tory Burch XS is Athleta XXS by the two brands' own charts. 5 of 5 Tory Burch sizes land on a different label at Athleta.

Both brands publish the body bust each size is cut for, so every row matches a bust, not a letter or a number.

Every Tory Burch size read across to Athleta. Letter sizes on the left, Letter on the right.

What wearers say

Charts describe a garment, not a fit. We do not collect fit reports for this category yet, so this table is the two brands' own claims and nothing more.
