LOULOU’S LIST: Oscar de la Renta doesn’t need stars to make his front row buzz. French fashion doyenne Loulou de la Falaise made an appearance at his show on Monday afternoon, after also hitting Carolina Herrera. De la Falaise is collaborating with de la Renta on a jewelry line, which she says was partially inspired by Catherine the Great. “It’s very deep in color, very Russian-y,” she said as she went backstage to greet her friend. It’s not the last chance to catch her: next on her list for New York’s fashion week is the Calvin Klein Collection show.
