Photos of Mary-Kate Olsen, Nicole Richie, Leighton Meester at Proenza Show During Fashion Week

Mary-Kate Olsen and Nicole Richie sat next to each other and chatted while Leighton Meester stood out in a metallic outfit at Proenza yesterday as Fashion Week nears its end. Diane Kruger and Taylor Momsen both hit up the Marchesa show before Taylor changed into a skirt for MCM's VIP party. At Tory Burch, Kanye West continued to take it all in before he's off to Paris Fashion Week where he'll show off the LV shoes he designed. Oscar de la Renta was spotted backstage with Barbara Walters and the young Barbara Bush as Bryant Park swarmed with celebrities. Not all the action was in the tents — newly engaged Rachel Bilson stopped by the Temperley London Store last night but wore gloves to cover any ring. Fab and Bella are right in the action, so don't miss their coverage.
