Diane von Furstenberg to Banana Republic clothing size
The short answer
Diane von Furstenberg XXS is Banana Republic 000 or 00 by the two brands' own charts.
Both brands publish the body bust each size is cut for, so every row matches a bust, not a letter or a number.

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.
