Mary-Kate Olsen Leaving Greenwich Hotel Pictures

Mary-Kate Olsen was bundled up in an oversize scarf as she left the Greenwich Hotel in NYC yesterday. The designer is wrapping up a busy Fashion Week that she spent sitting front row and partying with her fashionable pals. Mary-Kate kicked off the fun at Fashion's Night Out with Ashley, popped up at a V Magazine party at The Standard, and then checked out yesterday's J. Mendel show. On top of showing her support for other lines, Mary-Kate presented her own collection with Ashley, The Row. The duo aren't the only Olsens in the spotlight lately, though, since their younger sister Elizabeth is garnering plenty of attention between her almost racy GQ spread and her Toronto Film Festival premiere of Martha Marcy May Marlene.
