Abercrombie & Fitch to Marks & Spencer size
The short answer
Abercrombie & Fitch XXS is Marks & Spencer XS by the two brands' own charts. 2 of 8 Abercrombie & Fitch sizes land on a different label at Marks & Spencer.
Both brands publish the body chest each size is cut for, so every row matches a chest, not a letter.
