These are cute but run really small. My son is 3 and wears 3T or 4T in clothes (4T usually a little big on him), I ordered 4T and they were way too small. I didn't even try them on him, could just tell by the look of them. I wish they would have worked out because they are really cute. I had to return. If you order I would size up and maybe even up two sizes if your child is between sizes like mine is. I was going to order 5T but they don't have them.
