A flat cap is a rounded cap with a small stiff brim in front, originating in Northern England. The hat is also known in Ireland as a paddy cap; in Scotland as a bunnet; in Wales as a Dai cap; and in the United States as an English cap or Irish cap. Various other terms exist (scally cap,[1] cabbie cap, driver cap, golf cap,[2] longshoreman cap, ivy cap, train engineer cap, sixpence, etc.) Flat caps are usually made of tweed, plain wool, or cotton, while some are made using leather, linen, or corduroy. The inside of the cap is commonly lined for comfort and warmth.[3]
