Women's Long Sleeve Shirts — Button-Downs & Polos

Long sleeve shirts built around relaxed button-down silhouettes, easy structure, and a lived-in feel. The lineup includes the Mainstay Cotton Shirt in lightweight cotton plainweave, a breathable cotton-linen version, cropped long sleeve button-downs, and broken-in cotton twill styles inspired by mid-century men’s shirting. Clean tailoring, soft structure, and modern cuts give the category the feel of worn-in essentials made for layering, slow mornings, and the everyday.
