Nobody's mentioned it yet, but Kate Moss is confirmed to attend Vogue's annual Costume Institute Ball. The party takes place next week, with Cate Blanchett and Nicolas Ghesquiere of Balenciaga as the honorary co-chairs. Though we expect to see Cate, Anna Wintour, and probably Coco Rocha in Balenciaga, we're sure Kate Moss will wear something from her TopShop line to the party. Of course, she's already worn most of her TopShop dresses to other parties, years ago, but that's a secondary thing. After all, her hair color and her boyfriend are different, so the paparazzi photos won't get mixed up.
