Marks & Spencer to Tommy Hilfiger size
The short answer
Marks & Spencer XS is Tommy Hilfiger XXXS or XXS by the two brands' own charts. 4 of 8 Marks & Spencer 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.
On 1 sizes the charts land two or more sizes from the same label. Brands do not measure the body the same way, so on those rows treat the chart answer and the same label as the two ends of a range.
