My Big 13

Hey all!
Well, I just became a teenager on April 19 and for months I have been dreeming of an AMAZING party. My best friends and I love watching Mtv and chose to make my party a Black and White Affair when all girls wear white and all boys wear black. I knew this party would not be easy and because I took this party into my own hands much like the extravegent MY Super SweetSixteen girls and boys I want everything to be perfect. My question is what am i supposed to do with all my friends [70people] thats cool, goes with my theme, and original.

My party is May 6th so I hope for an answer fast!!
Help!
