Uniqlo to Farm Rio clothing size
The short answer
Uniqlo XS is Farm Rio XXS by the two brands' own charts. 7 of 7 Uniqlo sizes land on a different label at Farm Rio.
Both brands publish the body bust each size is cut for, so every row matches a bust, not a letter or a number.
On 4 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.
