Rising star Elizabeth Olsen had her two older sisters Mary-Kate and Ashley on either side to celebrate her Nylon magazine cover in NYC last night. The trio of Olsen girls posed together and chatted at their table during the event. Elizabeth is on the November issue cover, which showcases just one of her recent photo shoots, since she's also included in the Elle Women in Hollywood issue with Jennifer Aniston on the cover. Mary-Kate and Ashley are back in Manhattan after a trip to Paris Fashion Week where they showed their Row handbag collection and checked out the runways including Kanye West's first-ever show. Now that it's October, MK and Ashley's focus has shifted to Halloween, and the Olsen twins donned a series of silly costumes for their latest Style Mint video. Lizzie, meanwhile, is still making the festival rounds for Martha Marcy May Marlene with the Lincoln Center premiere coming up next week.
