Even though beauty products take the top tier in what we obsess over, we also love our clothes. So when designers and beauty brands match up to release some seriously sumptuous products, our hearts skip a beat. And lucky for us, 2013 was chock-full of designer collaborations with beauty brands. Alber Elbaz of Lanvin lent his quirky doodles to Lancôme, and we were all delighted. Anna Sui gave us a high-fashion Minnie Mouse collection. And we all squealed with glee when we spotted Isaac Mizrahi's polka-dot design for Tweezerman. It's a tough call, but someone has to be the best. Which collaboration had you most excited in 2013?
