Nothing ruins a great work outfit faster than a damp back and wilted confidence. If your morning commute involves a packed subway or a long walk from the parking garage, these lightweight pieces will totally change your world. Our favorite blouses, trousers, skirts and more have a barely-there feel that makes you forget you're even dressed. They breathe, move and drape without squeezing, perfect for busy fashionistas who don't have time for a costume change. Plus, flowy fabrics are polished enough for client meetings and cool enough for drinks after - no sweat stains involved.
