It fits an average 5yr old perfectly. Fun and well fitted product and made with good fabric. Sometimes kids costumes are thin and can rip, but this is a quality product. The details are really great. The cape runs a bit large, but we just pinned it up and it was just fine. The belt, mask and the padded chest really is very appealing. We had lots of compliments on the costume. It arrived really quickly and we've always been impressed with Rubies costumes.
