In the words of Bananarama, "This heat has got right out of hand." When it hits 100 degrees, the feel of any kind of clothing against your skin is enough to make you loose it—your calm, not your clothing (however much you want to). The answers to this oldest of summer dressing problems are linen, cotton, and silk. Better still: loose linen, cotton, and silk. All of which are on tap thanks to T by Alexander Wang's pre-Fall collection. Alexander Wang has nailed the slouchy T-shirt. Moreover, he understands the importance of mixing in natural fabrics. Which, if you have to set foot on a subway or tackle a walk-up, is no joke. Loose fits and a generous drape make the latest batch of striped linen tees, airy pocket tanks, and silk jerseys the next best thing to air-conditioning.
