WHITE HOT: Riccardo Tisci has earned a reputation for unexpected and trend-setting casting for Givenchy’s advertising: mixing girls and boys, celebrities and models. Last season, he added a frisson of controversy by casting a transsexual, and for next spring-summer, look out for strapping albino model Stephen Thompson. In pale black-and-white portraits shot by Mert Alas and Marcus Piggott, Thompson appears along with other Givenchy regulars like Mariacarla Boscono, Daphne Groeneveld and Iris Strubegger in overlapping exposures reminiscent of fashion photography experiments in the Fifties. During an exclusive preview, Tisci explained that he’s long admired albino people, reflected in the pale flesh tones that are recurrent in his fashions. “They’re very near my world,” he enthused. The campaign is set to break in the January issue of L’Uomo Vogue, French Vogue in February and several American titles in March. Tisci said the idea for his latest collections — and the campaign — dovetailed from a Robert Mapplethorpe photo of an alabaster Roman bust atop a stretch of leopard-print fabric.
