This is New York, not the desert

I know Ashley Olsen has a tendency to wear things that are a little wild, but seriously, wtf was she thinking when she put this ensemble together? This is what she wore to YSL's launch party for their new fragrance, Belle d'Opium. We're going to have to give her a what not to wear. She's looks like she's traveling in Saudi Arabia. This is a don't follow fashion moment!
