Amid the sartorial pomp and circumstance at New York Fashion Week, we noticed something shocking: Style stars, editors and It girls were all eschewing outrageous outfits in favor of simple sundresses. In the middle of September, no less. Rather than stow away their vacation frocks after Labor Day, the style set reinvented their sleeveless, printed frocks by layering them over classic white tees. How better to keep your mainstay in heavy rotation through fall? Add ankle boots and top with a denim jacket for a playful weekend look.
