I was afraid at first that this wasn't going to fit my 7yo- but it did- it has some stretch to it. However if he had been ANY bigger I don't think it would have. Love the hat and hair- he was soooo excited about it and it just completed the look. I also bought the beard/ mustache which was a total waste of money. I did a picture of it on him then it ended up in my pocket the remainder of the night.
