My son adores this costume. We tried it on for fit a week before Halloween, and he refused to take it off! Actually wore it all over town and got lots of compliments. He is a slender 3 year old, and it fits well with room underneath, so he'll be able to wear long johns or tight PJs underneath to go trick or treating if Halloween night is a cold one.

I would recommend sizing up if your child has a full build or is a true size 4-T as the fabric is not very stretchy and the seams do not seem very strong.

Construction is mediocre as best. There are hanging threads and the inner stuffing (that makes the muscle effect, is already coming out after just one wear. I would attempt to exchange, but I don't want to risk not having the costume on Halloween. I guess I'm going to have to try my hand with a needle and tread to patch it up. I would be afraid to put this costume in the washing machine.
