The beauty looks at the Veuve Clicquot Polo Classic were all about glamour, but there was one hairstyle that was the obvious favorite: the tousled wave. Whether they were paired with a turban like the one Rachel Zoe was donning, or styled in a vintage fashion à la Lauren Conrad, these wavy strands took center stage. The trick to this look is to hold your curling iron horizontally instead of vertically while you wrap the hair around it. A quick tug on the wave while it's still hot will further loosen it.

To get Lauren's style, brush the waves out lightly once they cool and part your hair to the side. Ashley Madekwe's strands can be achieved with a half-inch iron with the hair being curled away from the face, while Ashley Greene's can be teased up and pinned back for a cool-girl look. And for a trendsetting way to wave, pair beachy strands with an inky black turban like Rachel. These effortless curls look polished and cool, no matter how you decide to wear them.
