"This is a really cute idea for a costume. My son just turned 2 and though I admit a little big for his age, the costume was snug. My son wears a 3t and he is slim. Additionally, it was a bit short. Luckily I can hide that with socks. Otherwise, it was a great purchase and I am happy with it. It's hard when you can't try it on and what fits your growing child one day may not fit the next."
