One of the most exciting parts of Couture Fashion Week: Chanel nail polish. And in this particular case, you don't have to wait to buy the gorgeous apricot shade that came down the runway. The models' fingertips were polished with Emprise Nail Colour ($27), a limited-edition hue from the new Spring 2013 collection. Best of all, it's already available online and at Chanel counters.
