This button-down borrows from his side of the closet, but somehow looks even better on you. Cut from crisp cotton with a clean, straight fit, it has a hidden placket with mother-of-pearl buttons and French cuffs. Look a little closer and you’ll notice the quieter details: subtle white-on-white stripes and an ivory GWYN logo embroidered at the hip. Wear it tucked into something high-waisted, like The Universal Pant or The Westminster Skirt, or leave it loose over The Classic American Jean.
