And the answer is Erin Wasson. See this is how you make a name for yourself! Who needs a PR agent when you got this going on? Because until two seconds ago I had no clue who this chick was. Then she wears an assless dress to a Vogue Young Hollywood party and suddenly she's featured on Guess That Ass and the hottest thing in Hollywood. Just goes to show that when in doubt flaunt your ass. Well played Erin. Well played.
