A barrel cuff is a style of buttoned cuff found on mens formal dress shirts. The barrel cuff is often considered more formal than a simple button cuff yet less formal than a French cuff. Like a button cuff the barrel cuff uses buttons rather than cufflinks to join the two sides of the cuff together.
A barrel cuff is differentiated from other button cuffs by the orientation and number of buttons. The two buttons of a barrel cuff are positioned next to each other and lay in parallel to the seam of the cuff.
