Surf giant Billabong held its annual 'Design For Humanity' benefit at the Avalon in Hollywood last night. Beauties like Estella Warren, Sanoe Lake and Sara Paxton were among the stylish crowd browsing (and in some cases bidding on) art and one-of-a-kind Billabong swimsuits.

A runway show of Billabong's surprisingly edgy, ultra '80s rocker swimwear preempted a performance by Airborne Toxic Event.

All proceeds benefit Charity:Water which brings developing nations clean drinking water.
