"I bought this costume for my son who is 2. I bought the 2T size because that is what he usually wears. When it arrived in the mail, I couldn't believe how ridiculously small it was. I could tell before even puting it on him that it was not going to fit. The pants and sleeves were so incredibly short on him and the body of the costume fit very tight as well. The cape also looked like it could only fit a small infant (I'm talking newborn infant). There was no way that the cape was going to fit at all. My advice...order at least one size up. The overall quality was just ok."
