"It says it's for ages 4-8 but it's more like 4-5. I bought 2 of this costume for my 5 and 7 year olds (both average sizes of 5T and 6-7) and the costume fits my 5 year old but it's too small for my 7 year old (the sleeves are about 2 inches short and the helmet doesn't fit at all). Also, there are MANY sharp edges where the decorations attach to the helmet and arm guard - both of my childrens' heads and arms got scratched when putting these on (I've had to put tape/padding in order to avoid repeats). I would not recommend this costume unless you're only buying it for the sword/axe."
