Disney Princess or Medieval Queen?

I need ideas for my Halloween costume this year. I bought some Halloween fancy dress costumes last year after Halloween but I can’t decide which I want to be! I have a Belle costume, a Cinderella costume, and an Aurora (Sleeping Beauty) costume. But none of them are really screaming ‘Wear me!’ at me. I have the clothes to be a Renaissance Queen, but I don’t know about that either. I usually go to the Renaissance Fair every year, so I know the costume, but I wear it too much! Oh, so many fancy dresses and so little time to decide because I have a costume party this year.
