Q: Pink Bat-girl is a hit at our house. She loves to dress up. Costume is a little flimsy but will last through the Halloween season and maybe some dress-up after. Skimpy and thin so plan on wearing something under it. (I wish we had bought a size larger) Don't be fooled by the cape it does not go over the shoulders, only behind the back. It is very cute and my 7 year old daughter loves it.
A:
Positive
