Jason Wu, one of the darlings of the New York fashion world, celebrated a double success Friday: his latest collection made a splash and he sold a controlling stake in his business. The Wu woman of spring/summer 2015 is discreet, elegant and sensual, dressed in silk dresses and shirts, an oversized white coat, transparent lace, wrap skirts revealing a bit of thigh and a sleeveless olive suede dress with a plunging V-neck.
