Kristin's Pricey Kicks

MTV reality star Kristin Cavallari made the scene last night in Hollywood. The former "Laguna Beach" star was caught leaving the trendy S-Bar and strolling down Hollywood boulevard to her next stop, the Cinaspace Club. Kristin was in black from head to toe, from her black leather jacket to her $640 (!) Yves Saint Laurent Tribute pumps. I do have a question about this ensemble - why wear super-expensive shoes if you're going to wear them with cheap, snaggable tights?
