"I got this costume for my 8 yr. old brother. It fit well, and looked great. The glasses light up and look really cool (a lot of people commented on them). The only problem I saw was attached to the glasses are the battery compartment. There isn't a pocket or anything on the costume to put it in. We fixed this by having him wear pants under the costume with a big enough pocket to stick it in, but is was still a little tricky to get it in there."
