IVY CAPS / FLAT CAPS An ivy cap or flat cap is a rounded men's cap with a small stiff brim in front. Cloths used to make the cap range from tweed and leather to cotton driving caps for summer wear, sometimes featuring air vents. The flat caps were almost universally worn in the 19th century by working class men throughout Britain and Ireland, and versions in finer cloth were also considered to be suitable casual countryside wear for upper-class English men, hence the contemporary alternative name golf cap. Today, the style has remained popular among certain groups of people in Europe and North America. The ivy cap / flat cap is sometimes associated with older men, but has been popular among some segments of younger people today. The style has also been favored by the young Hollywood trendsetters as well as with musicians. The ivy flat cap / golf cap, has also appeared in the hip-hop subculture, worn back-to-front, proving very popular in recent years.
