We are going to the MNSSHP in a few weeks and I had a question about costumes. My daughter originally didn't want to dress up but has now changed her mind. The problem is that the costume she wants to wear is not Disney related. Does it matter? It's just a fancy black dress that actually lights up. I'm going to buy it for her if we won't get weird looks for having a non-Disney related costume. She's twelve and it's the first time I've seen her excited about this trip!
