After a long-fought battle against red-carpet royalty like Diane Kruger, Emma Stone, and Kate Middleton, it was hot-to-trot vampire Kristen Stewart that came out on top as the red-carpet queen of 2012. Kristen's year was quite the roller-coaster ride, but she managed to keep her head (and her heels) high while promoting her trio of films: from the whirlwind Breaking Dawn Part 2 press tour to her breakneck schedule while plugging Snow White and the Huntsman and On the Road, Kristen hit the red carpet in a succession of sexy looks, including high-slit dresses, sheer gowns, and microminis. We're celebrating Kristen's win with a look back at some of her most memorable looks from the past 12 months — not including Converse sneakers. Click through to see them all now!
