G-Star RAW to Reformation jeans size
The short answer
G-Star RAW 24 is Reformation 25 by the two brands' own charts. 13 of 16 G-Star RAW sizes land on a different label at Reformation.
Both brands publish the body waist each size is cut for, so every row matches a waist, not a tag.
On 5 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.
