I bought this costume for my son who will be 7 years and I dress in 8 years for over 6 months. It would be easy for a child 10-12 years. I contacted the seller 3 times including twice in English on its website and I remained unanswered. The actual size does not correspond to the indicated size .... This transaction I was quite upset because I have it back in the UK (fee back to my very high load), I could not exchange it because I never had any contact with the seller. In short, deplorable transaction; discouraged ....
