"My son fell in love with this (which is the only reason I bought a 2-piece costume for over $30). I was in a hurry, so I didn't read the reviews...it runs way, way small. Order 2 sizes bigger and beware the mask is not very soft inside, it hurts his face. I'm a little annoyed with the costume but he had such a hard time deciding I ordered the larger size, am returning the smaller size and will be more careful next time."
