Brooks Brothers to Tommy Hilfiger size
The short answer
Brooks Brothers XS is Tommy Hilfiger XXS or XS by the two brands' own charts. 3 of 6 Brooks Brothers sizes land on a different label at Tommy Hilfiger.
Both brands publish the body chest each size is cut for, so every row matches a chest, not a letter.
