Whitney Port has officially transformed from a Los Angeles "Hills" girl to a New York "City" fashionista. Hitting up Louis Vuitton's event, the coast-to-coast reality starlet wore a sophisticated, black sleeveless number with cut-out sides and a very socialite-like antiquated pearl necklace. Boho chic to New York fab in 2.2 seconds -- almost as long as "The Hills" girls remain friends.
