Acne Studios to G-Star RAW jeans size

The short answer

Acne Studios 40 is G-Star RAW 29 by the two brands' own charts.

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

Every Acne Studios size read across to G-Star RAW. US numeric sizes on the left, Waist size on the right.
