Athleta to Diane von Furstenberg clothing size
The short answer
Athleta XS is Diane von Furstenberg S by the two brands' own charts. 4 of 6 Athleta sizes land on a different label at Diane von Furstenberg.
Both brands publish the body bust each size is cut for, so every row matches a bust, not a letter or a number.
