Yesterday, in the midst of Paris Fashion Week, Carine Roitfeld threw a cocktail fête at Hotel Shangri-La to celebrate CR Fashion Book’s second, ballet-themed issue. When the New York party went down, we hadn't yet learned that the magazine would be stuffed with models that had hair dancing in the wind and even a monkey suited up in Armani, but it seems the party attendees in Paris took note. Jessica Chastain, Jessica Alba, Karlie Kloss, and Amanda Seyfried were all in town for the party, and we tagged along with photographers to catch a pantsless Kate Moss, Karl Lagerfeld wearing sunglasses, and, of course, Kanye West.
