I bought my son this costume. He's 8 years old and the costume is S, ie supposedly to 5 years. Well, my son is a shirt, but even then the top part is large enough, the trousers also has a good length and I would be after the age gone like the Arwen costume, probably three children have since reingepasst. Toll processed, looks attracted the same as in the picture, very nice :) As I said, my measure before ordering and you'll be fine
