"I ordered this costume in a 4 - 6x after buying the same costume at a local store that was a 4t and was a little small on my son who insist on being a DOG for Halloween. I was so excited when this got here, then I put it on my son and it was 2 sizes smaller than the one I bought in a smaller size at the local store. It was more like a 3T. The legs were too short, the foot part came up to his ankles and sleeves were more like 3/4 sleeves and the zipper barley went all the way up. I am sending this back and very disappointed. The packaging said it was an XL, I would like to know what XL means to these people that made the costume!"
