Alexander Wang used lighter treatments to propel his zip-up leather jackets and classic bomber silhouettes into spring. For added comfort, the sportswear-inspired outerwear was lined with soft fabrics such as jersey or terry cloth. Shirts and vests were rendered in perforated leather overlaid with a black-and-white grid print. Variations on Wang’s staple short-sleeve baseball shirts included one in graphic black-and-white panels with minimal cutout pockets. Having started out as a T-shirtline, T by Alexander Wang is looking increasingly like a complement to the main line. This season, its offerings include sweatpants with a leather waistband, graphic swimwearshorts and nylon or leather windbreakers.
