Fashion Party Pics: Jessica Biel, Kate Upton, and Gaga

Fashion crowds had a busy Friday night, starting with the premiere party for Mademoiselle C., Fabien Constant's new documentary about Carine Roitfeld. The Roitfeld crowd —  Vladimir and Julia Restoin-Roitfeld, Giovanna Battaglia, and Terry Richardson — was out in full force; Kate Upton, Karlie Kloss, and Kanye West stopped by, too. Farther uptown, Saks 5th Avenue hosted a "dinner" (more like an endless Champagne waterfall with a smattering of tiny hors d'oeuvres) for Dior and Jessica Biel. The store's entire third floor was decorated to look like the set of Raf Simons's fall show, complete with cloud carpeting and enormous silver balls.
