"My son wears 10-12 but after reading previous reviews I decided to buy the next size up which I'm glad I did. So buy a bigger size than what your child usually wears. But, no matter what size you get keep in mind the wrist bands are TOO SMALL! We ended up buying REAL stretchable writstbands and sewing the wwe pictures on. The picture makes the hat look real but it's not. It is really flimsy so we'll have to iron and starch it so it stays straight. Based on quality the price should be lowered to $14.99."
