T went sleeker and shinier for Fall. "I wanted all of the hardware to disappear," Alexander Wang explained at his showroom. The lower-priced collection grew out of T-shirts and sweats, and this season it looked more full of them than ever before. Funneling his more refined energies into his mainline menswear and allowing T its sportiness meant the designer could tinker here with fabrics and fabrications. Rayon replaced cotton, polyester was paired with satin, and jersey was bonded to neoprene. It lent the whole lineup a slightly mutant feel. T-shirt collections are proliferating wildly, but T continues to make a case for itself. The look remains simple, but touching is believing.
