14th Birthday Party Ideas

Hey, I am having a party for my 14th birthday in like a month time. I have a slight idea of what I want to do; I am going to invite 33 people and I am going to have a dinner and then after dinner have a dance floor and music so we can party! The only help I really need with is what my theme should be. I thought of maybe black and white, or, black and silver, but I really need something better. Please help. Thanks so much. =]
