Vanessa Hudgens’ ballerina topknot adds height and elegance. It accentuates her subtle cat-eye makeup and highlights her rosy glow by pulling hair up and away from her face. Spritz some hairspray on a toothbrush to smooth back any flyaways. Just, please, use a new one (or maybe even your boyfriend’s or roomie’s … if you’re in the mood for an evil trick).
