G-Star RAW to Guess jeans size

The short answer

G-Star RAW 24 is Guess 25 by the two brands' own charts. 7 of 9 G-Star RAW sizes land on a different label at Guess.

Both brands publish the body waist each size is cut for, so every row matches a waist, not a tag.

Every G-Star RAW size read across to Guess. Waist size sizes on the left, Waist size on the right.
