Unless you've been living under a rock for the past year, you know that teen vampires are all the rage right now. The Twilight and Sookie Stackhouse book series have brought vampires back from the dead and into pop culture. Teens might like to play off the current vampire trend, which shouldn't actually require much special costuming. There's no need for a Dracula cape and slicked back hair. To pose as a member of the stylish Cullen gang from "Twilight," for instance, teens just need a pair of false vampire teeth, white pants and shirt and some glittery lotion. A dab of fake blood on the chin is the perfect finish for the ominous ensemble.
