If a new restaurant, Armani/Ristorante on Fifth Avenue, weren't enough to attract guests (on a competitive night) to kick of Fashion Week with Giorgio Armani, then a preview of the forthcoming "Richard Hambleton–New York" exhibition was the kicker. It was enough for Bruce Willis, Derek Blasberg, Rachel Zoe, and Olympia Scarry. The show opens September 15 at 560 Washington Street.
