GAP denim overalls for 18-24 months Size 90 Shoulder straps adjustable in 2 steps with buttons Worn twice for USJ and Halloween. It fit my relatively sturdy child, who usually wears size 90, snugly. The crotch buttons felt like they might burst when sitting, so it might be better for a slimmer child or someone looking for size 80. However, it's simple, very easy to use, and cute.
