This costume is adorable on our baby. It fits him perfect at this point in time, about 1 month away from Halloween. He's 3 mos, weighs about 12 lbs. The quality is fine for its purpose. My only gripe is the manufacturer needs to relabel the "1-9 mos" There is no way, this costume will fit our baby at 9 mos. I'm hoping he doesnt grow too much more this month, so he can fit into it before he gets too big.
