What Is a good Teen Girl Halloween Costume?

I am 14 and my friend i want to go as the same costume or something that is like the other. But we have no Idea what? We want something original but not weird. We are both kind of girly, and we dont want something slutty or expensive. Preferably homemade... I have fairy wings, a egyptian costume, pirate costume, fluffy boa, black tutu, and fancy dresses... all stuff i could use. Help Please! Happy Halloween Btw!:)
