For perfectly undone waves, look no further than the gorgeous style at Jill Stuart, created by James Pecis for Oribe.

"We didn't want the hair to be big, but we wanted it to be full," Pecis says. He loosely curled hair in random directions using a 1-inch curling iron. Then, he sprayed Foundation Mist into his hands and ran them through the models' hair to break up the curls, and topped it off with a mist of Dry Texturizing Spray.

The braids at Mara Hoffman, created by Thomas Osborne for Catwalk by Tigi, are the stuff Pinterest dreams are made of.

Models at Jason Wu sported a sleek, simple style created by Odile Gilbert for Kerastase -- the first time the designer has had models wear a down hairstyle.

To create the carefree, lived-in style at Richard Chai, Unite Editorial Director Kevin Ryan used a combination of Unite Tricky Spray and Expanda Dust. He then created an intricate bun/ponytail hybrid that required forceps and (we're guessing) a lot of patience.

We're personally just looking forward to being able to wear our gym headband to work and calling it "runway-inspired."

To create the killer topknot at Monique Lhuillier, Stephen Churchill Downes for Moroccanoil pulled models' hair into a tight ponytail, misted it with hairspray and then wrapped it around to form a loose, piece-y bun.
