EXCLUSIVE AT NET-A-PORTER. Arch4 sources the finest Mongolian baby goat cashmere for its pieces so they really last and are exceptionally soft - it's GOTS-certified organic, too, so it's gentler on the environment. Spun from a warm 'Mahogany' version, this top has a slightly loose silhouette with a polo collar. Adjust the lustrous mother-of-pearl buttons to your desired neckline and style it with a tonal skirt or tailoring. This product was created using Considered Materials. Find out more about
