"It's time to bring sexy back," said Alexander Wang. But hasn't he been hard at work at that task for seasons now? "A louche kind of sexy," he amended. So out went the mesh, perforated leather, and other athletic references from Spring, and in came an elongated scarlet velvet tuxedo jacket, a coral washed crepe one-sleeve draped cocktail dress with hook-and-eye closures, a light blue denim bustier with black velvet bra cups, and a gold-stud print trench. Wang still loves that effortless, thrown-together look, but the Fashion Fund winner is growing up, and so are the silhouettes and the sensibility of his clothes.
