Nike to Athleta clothing size
The short answer
Nike XS is Athleta XXS by the two brands' own charts. 3 of 6 Nike 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.

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.
