Thankfully the previous reviews forewarned me that this costume runs a little large. I was all set to hem it for my 4 1/2 year old. Had to hem about 3 inches on the bottom and about 4 inches for the sleeves. She wouldn't wear the wig so I can't tell if it's too tight or not like others have mentioned. I did have to restitch one of the velcro pieces in the back to make it lay flat so it would catch the other side more consistently. The fabric was sturdy enough for several days of dress up and with the extra length that I can take back out this costume will service other Halloweens or dress up days.
