On Saturday afternoon, Details is turning the Meatpacking District into a bigger clusterfuck of shopping and eating than it already is. Publisher Chris Mitchell has wrangled Peroni into sponsoring dozens of stores and eateries as they offer discounts and other meaningless offers to lure you into their shops as part of what they're calling a "Block Party." Gift with purchase at Catherine Malandrino. Ten percent off at Tracy Reese. Haircut and two products for $110 at Bumble & bumble. Oh, and on the rooftop of Hotel Gansevoort, experience the 2004 craze "pop-up shops" — and meet Kenneth Cole. Where you can take turns throwing people to the street.
