Yesterday was the first official Burberry Day in New York City, and was celebrated appropriately -- with serious style. According to WWD, celebs like Claire Danes, Hugh Dancy, Orlando Bloom, Molly Sims, Rose McGowan, Blake Lively and Penn Badgley braved the inclement weather to attend a party toasting the brand's new New York HQ on Madison Avenue, as well as the addition of a lighted Burberry sign to the NYC skyline.

The party, held atop the New York Palace Hotel, included live music and a light show, as well as tunes spun by Alexa Chung. But, it was lacking in one very important aspect -- booze. WWD reports the party was dry by 9:30, leading some guests to duck out early.
