In celebration of its new NY headquarters, Burberry lit the cityscape with bright lights and a fashionable soiree filled with bubbly and a guest list PR people would kill for. There were a ton of looks to choose from, but I narrowed it down to five. Lily Donaldson showed off her stems in a white chiffon minidress; Alexa Chung styled her printed sheath with a belt and blazer; Leigh Lezark looked sexy stealth in a ruched eggplant frock and sharp heels; Claire Danes accessorized her gray dress with bold adornments; and Blake Lively looked cunning in a loose blazer and mini. All Burberry, all beautiful. Divulge: which Bailey supporter do you prefer?
