New York Fashion Week can get so busy that you forget about the things that matter. Like eating. And sleeping. And cleaning. So it would be easy to let something as mundane as a birthday slip through the cracks. Not for the Rodarte designers Laura and Kate Mulleavy. The sisters gathered their nearest and dearest together for an intimate post-show party at Chez Andre in The Standard, East Village. After Lindsey Wixon, Atlanta de Cadenet and Kim Gordon had a chance to offer their congratulations, Laura brought out a cake, emblazoned with Jim Morrison’s visage, to wish Kate a happy birthday.
