A heat wave descended on New York just in time for fashion week, and show-goers are giving us a lesson in extreme weather dressing, opting for sheer, barely-there clothing and summer post-Labor Day whites. Of course, there’s also some diehards in the mix, so don’t be surprised to see black leather and even a shearling or two. Follow along as Phil Oh heads to the week’s biggest shows—Coach, Helmut Lang, Proenza Schouler, Altuzarra, Tory Burch, Willy Chavarria, Luar, and many more.
