Fall '08 brings a wave of exciting new looks, with designers (and stylists) showcasing easy-to-emulate styles that can be worn right off the runway to the office or a night out on the town.

One of these key styles (that I think everyone should experiment with) is the messy updo, which works to balance the rich fabrics and jewel-toned makeup of the season beautifully. Slept-in, textured hair, visible pins, loose locks — almost anything is game.

Just be sure to wear this look with well-groomed brows and tailored silhouettes, so you always appear on-trend and not disheveled.
