What fairytale character wears a silver dress?

I have a drama banquet to go to tomorrow and it has a fairytale theme. We are supposed to dress up like fairytale characters but if we don't want to do that we can just wear a dress. So I was just planning to wear this nice sliver dress I have but then I found out most people are actually wearing costumes so I was wondering if there are any fairytale characters who wear silver dresses that I could say I am.
