If it's not obvious enough, I'm completely obsessed with Blake Lively's hair. Yes yes, I know that she wears hair extensions, but she's one of very few people that can really rock that much length. She was spotted last night looking red hot on the red carpet at a party for Vertu in New York City with perfectly smooth, straight hair, a look that we don't often see on her. Weeks before, we saw her on the set of Gossip Girl with her typically wavy hairdo, and months before that she wore her hair styled in a full head of curls for the New York Premiere of Sherlock Holmes. Out of these three looks, which do you think looks the best on Blake?
