Kanye West and Sarah Jessica Parker attended the launch of Maison Martin Margiela For H&M last night in NYC. SJP and Kanye gathered inside 5 Beekman Street, an under-construction spot formerly known as Temple Court which will soon become a hotel. They mingled with other celeb attendees like Julianne Moore and her husband, Bart Freundlich. There were plenty of models in attendance, too, and we caught up with Doutzen Kroes on her way in. She spoke about her excitement for the upcoming Victoria's Secret Fashion Show, and also touched on her and husband Sunnery James's plans for Halloween with their one-and-a-half-year-old son, Phyllon. She said, "I'll probably put him in an outfit this year!" The stars were treated to an interesting evening full of performance art, Champagne, and a chance to shop the collection. The full Margiela For H&M line is available in stores Nov. 15.
