This is a great quality costume, I usually don't like store-bought costumes but I was really impressed with the look and material used for this one. The pin-stripping goes all the way around the costume, no cheap solid color panel on the back. It's a jump-suite with a slit in the back with velcro tabs to keep it closed. The bow-tie is held on with velcro as well. That said, my son is a skinny 2.5 year old and he just barely fits into this with thin clothes on underneath. The legs are a bit long on him, which I can fix no problem, but the body area JUST fits him. I would be nervous about recommending this costume to anyone with an actual 3/4 year old which is the size it's supposed to be. He has a larger-sized head for his age, but the hat fits him fine, again I think it might be small on an older child.
