Bow Poplin ShirtDetails: Put a bow on it. Our Button Up is dress shirt inspired with a front placket and hidden buttons, finished with the cutest little bow detail on the top button and a row of bow buttons along the cuffs. A box pleat at the back adds just the right amount of shape. Fit: We recommend true to size for that perfectly oversized look, or size down for a slightly more fitted feel. Fabric: Made from 100% cotton in a relaxed fit.
