Vuori to GU size
The short answer
Vuori XXS is GU S by the two brands' own charts. 7 of 8 Vuori sizes land on a different label at GU.
Both brands publish the body chest each size is cut for, so every row matches a chest, not a letter.
On 2 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.

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.
