Diane von Furstenberg to Reformation clothing size
The short answer
Diane von Furstenberg S is Reformation XS by the two brands' own charts. 3 of 5 Diane von Furstenberg sizes land on a different label at Reformation.
Both brands publish the body bust each size is cut for, so every row matches a bust, not a letter or a number.
