MINIMALIST MUSTS. Our Frock and Skirt Leggings collection all feature a jersey-rayon blend fabric that can be washed and worn over and over again without pilling or fading. Adored for being casual and basic, STAPLE items are especially versatile. Frock dresses can be dressed up and down, worn belted or loose. Skirt Leggings lend a chic, slimming canvas to any top — or any kind of busy day. The ultimate soft, comfortable STAPLES can be worn and styled differently, day after day.
