A slew of celebrities came out this week in support of a good cause.
For the third year in a row, Paper Magazine and H&M sponsored the Fashion Against AIDS Collection, an event meant to emphasize the need for safe sex.
Those in attendance included Adam Lambert, Benji Madden... and Hugh Hefner's busty twin girlfriends, Karissa and Kristina Shannon.
Ogle photos of the group below and visit our fashion store to see if you can purchase any of this attire. Come on, who wouldn't wanna look like Hef's gal pals?!?
