A cotton belted shift dress is reliable in a way that matters when you are building a wardrobe of things you actually reach for. The shift cut is straightforward and forgiving and the belt gives you definition without requiring anything to be tight or fitted. Cotton takes dye well so the colours tend to be clean and true. The fabric has enough structure that it does not feel flimsy but enough give that you can move properly. Layer it over a long-sleeved shirt in winter or wear it bare-armed when it is warm. These are the cotton belted shift dresses that work year-round because the fabric is honest and the silhouette is genuinely useful.
