My beautiful 22 year old went from pink and lacy princess to shaved head and punk clothes. She was a beautiful princess and she is now a beautiful punk. Have faith in your children however they imagine themselves. So long as issues like entitlement are addressed and concepts like marketing are taken into account, let them be who they choose to be. There are plenty of explorations of princess themes that send positive messages, the book Paperbag Princess, and the movie Enchanted to name a few. Love and support them now matter what their favorite colour is.
