Good American to Uniqlo jeans size

The short answer

Good American 6 is Uniqlo 28 or 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 Good American size read across to Uniqlo. US numeric sizes on the left, Waist size on the right.
