While sweatpants and fashion don't usually mix, designers this season managed to make sweats chic. Revamped by designers like Alexander Wang, Elie Tahari, and Isabel Marant, sweatpants became one of the most versatile pieces on the spring 2010 runways. To keep your look more sophisticated than sloppy, try pairing these items with structured blazers and high heels -- and blazers, skirts, or dresses made of sweatshirt-like fleece are a comfortable and easy choice for those who still want to leave the sweatpants at the gym.
