You've got to belive it! Been hearing about it. But I wasn't sure. New York's most fashionable will be running all over the city to cover the shows, so it's no surprise that Alexander McQueen is joining the fray with a weekend pop-up for his latest Target collaboration. Preview Feb 14 to 15. McQ will be available in stores in early March. Available only for this weekend at Market, St. John's Center, 330 West Street (at West Houston Street)no phone.
