GOTHIC GIDGET: Riccardo Tisci headed to the beach for Givenchy’s spring-summer ad campaign. But trust the Gothic designer to bring a dark twist to the proceedings: Gisele Bündchen, Mariacarla Boscono, Chris Moore and Simone Nobili are shown posing with black surfboards against darkening skies. The designer described the atmosphere as “the expression of a love story between a surfer and a mermaid.” Lensed by Mert Alas and Marcus Piggott, with hair by Luigi Murenu, makeup by Lucia Pieroni and layout by M/M, the campaign will break in February issues of Vogue, W and other magazines.
