Size small = a 7/8 (big boys size) in this particular t-shirt, so 9/10 = medium ect. It is your average t-shirt, not heavy like a winter t-shirt, not super thin cheap t-shirt material either. Worth the almost $12 just to see our kid so excited! Lol! Total happy dance from him when we opened it, and at the end of the day that's what it's all about.
