Reformation to DESCENTE clothing size
The short answer
Reformation XS is DESCENTE M by the two brands' own charts. 3 of 3 Reformation sizes land on a different label at DESCENTE.
Both brands publish the body bust each size is cut for, so every row matches a bust, not a letter or a number.
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.
