New York and Paris are two of Peter Som’s favorite cities. For fall the designer merged the two effectively with a lineup — presented as a digital runway show — that nicely captured Gotham’s urban chic and the insouciance of the French capital. Or as Som put it in his show notes: “an electric mash-up of early Eighties NYC downtowners photographed by Amy Arbus, mixed with the romance of Paris.” Two such examples included a black-and-white patchwork bustier dress that incorporated a painted dot fabric on the shoulders and waist, with a skirt in layered chiffon over sequins; and a leopard-print sweater with a floral sequined pencil skirt. Some of Som’s new prints were equally appealing, including an abstract floral that had a graffiti feel à la New York’s streets during the Eighties. As for the party dresses, they had a soft, languid touch and sense of lightness that young, fashionable women in any city would appreciate.
