<P> The bowler has had varying degrees of significance in British culture . Popular among the working classes in the 19th century, from the early 20th century, bowler hats were commonly associated with businessmen working in the financial districts, also known as "City Gents". The traditional wearing of bowler hats with City business attire ended during the 1970s . During modern times bowlers are not common, although the so - called City Gent remains a stereotype of Englishmen, wearing a bowler and carrying a rolled umbrella . For this reason, two bowler - hatted men were used in the logo of the British building society (subsequently bank), Bradford & Bingley . </P> <P> In Scotland and Northern Ireland the bowler hat is worn traditionally by members of the main Loyalist fraternities such as the Orange Order, the Independent Loyal Orange Institution, the Royal Black Preceptory and the Apprentice Boys of Derry for their parades and annual celebrations . </P> <P> The bowler, not the cowboy hat or sombrero, was the most popular hat in the American West, prompting Lucius Beebe to call it "the hat that won the West". Both cowboys and railroad workers preferred the hat because it would not blow off easily in strong wind while riding a horse, or when sticking one's head out the window of a speeding train . It was worn by both lawmen and outlaws, including Bat Masterson, Butch Cassidy, Black Bart, and Billy the Kid . In the United States the hat came to be known commonly as the derby, and American outlaw Marion Hedgepeth was commonly referred to as "the Derby Kid". </P> <P> In South America, the bowler, known as bombín in Spanish, has been worn by Quechua and Aymara women since the 1920s, when it was introduced to Bolivia by British railway workers . For many years, a factory in Italy manufactured such hats for the Bolivian market, but they are now made locally . </P>
