The Sienna is an elevated take on a utility shirt dress. Effortlessly elegant, its patch pockets, epaulets and self-tie belt are considered touches to its unstructured shape. Its luxe, satin-back crepe fabric is cleverly composed from a new fabric Ecojilin, which is made from recycled cotton fibres. Style it for work or dinner with the top buttons open and the sleeves rolled up for that intentionally undone look.
