Last Thursday, supermodel Naomi Campbell visited Alexander McQueen’s Meat Market flagship store, 417 W. 14th St., the day after the cutting-edge fashion designer killed himself in London. She was ushered in by a McQueen employee wearing one of the fashion icon’s signature skull-print scarves, left. Mourners left flowers in front, while staffers covered the store’s window with white paper. In addition to Campbell, McQueen’s dramatic outfits were favorites of Madonna, Lady Gaga and Michelle Obama.
