SIMPLE CEREMONY: Wedding bells were set to ring Thursday night, but ever so quietly, for Nina Griscom and her longtime beau, Leonel Piraino. Griscom opted for a small, simple ceremony in the Fifth Avenue apartment of her parents, former Ambassador Felix and Liz Rohatyn. Former New York mayor David Dinkins officiated. Afterward, the group of immediate family and a few close friends were to head to the nearby Knickerbocker Club for a celebratory dinner. But Griscom didn't plan to buck all tradition: Though eschewing a full-length gown with train, the bride ordered a custom-made Champagne silk shantung dress with matching jeweled jacket, designed by — who else? — Vera Wang
MANCHESTER MADNESS: The empty Laurent-Perrier bottles had barely been cleared from London's Serpentine Gallery, which hosted its annual summer party Wednesday night, before art world hotshots were already on to their next adventure. Last night, Matthew Barney, Miuccia Prada, Stefano Pilati, Sadie Coles, Doug Aitken, Trisha Donnelly, Liam Gillick and Olafur Eliasson were in Manchester for the world premiere of a group show called "Il Tempo del Postino." The experimental, live performance, which featured 15-minute segments dreamed up by artists including Barney, Aitken and Donnelly, took place at the city's opera house during the first biannual Manchester International Festival. The show, cocurated by the Serpentine Gallery's co-director Hans Ulrich Obrist and artist Philippe Parreno, will run for three nights. In February, it will move to Paris' Theatre du Chatelet, and will later go on a world tour.
