I bought this for my nieces birthday present, she was having a princess birthday party for her fourth birthday, I bought an extra small 4-6.  She opened it in front of everyone, imediatly put it on and it was wayyyy to big, she cried and took it off.  Everyone involved is devastated, and I am out almost thirty dollars.  I am so mad, and there are no returns.  Dont buy this costume unlees it is for an adult 4-6.
