Alexander Wang is no longer the new kid on the style block, and this season, he cast some of the biggest names in modeling: Joan Smalls, Liu Wen, Gisele Bundchen, Karolina Kurkova, Shalom Harlow, and more. They sported a beauty look that was easy, wearable and slightly tomboyish — something that works equally well on the runway or the sidewalk. Check out our video for a sneak peek at Alexander's newest nail polish collaboration with Sally Hansen, plus so much more from behind the scenes.

Backstage at Rachel Zoe's Fall 2012 show, models sported a cool, downtown vibe with messy and sexy hair. Makeup was inspired by Kate Moss, Marianne Faithfull, and a little Mick Jagger — a high-drama look that begs to be seen on stage as well as the runway. Rachel herself was wearing one element of the look just days before the show. Watch now to see what made Rachel hand-select a key part of her collection's beauty look.
