"I can't wait for my daughter to wear this for Halloween. I read the reviews before buying and was happy with my purchase. My daughter was very excited when she tried on the costume and it lite up! That was very exciting to her. I did have to cut out the elastic on the arms like others have but that was no big deal. I think she will wear this for halloween and then it will be well used in our dress up box into the future. As for the size, it did run small but it fit my daughter just fine, she is slim and will fit her for some time to come."
