Beauty And The Beast Theme For Friends 15

My friend is having a 15 and she thinks she wants her theme to be beauty and the beast and it sounds nice shes gonna have a yellow dress like belles and he main chambellan is gonna wear a costume like the prince but she dosent know if the theme is tacky or too cheezy and she dosent know if she should have cadets or damas and chambellanes as her court of honor. Cadets are good and everything but i think your so limited to what you can do with cadets what should she do?
