I bought this for my 43" tall, 45lb 5-year-old boy. It fit like it was custom-made! (child s)
This costume is great only thing is that it runs small. I ordered up and the costume fit great! If I would have went by the size chart I would have ordered a small, I ended up ordering a large and it fit with room to grow. My son in 61/2 years old slim build and he is just over 4 ft. (49 inches). He loves this costume we already have gotten our $$ worth!! Also it's very nice how the mask isn't attached to the body suit so he can wear either or.
