[1]It’s difficult to find a piece of clothing as widely accepted, worn and loved as jeans in the world. The classic symbol of the American West is now a main item in closets around the world. But why?
[2]The reason for jeans’ success has as much as to do with their cultural meaning as their physical construction.
[3]Invented by Levi Strauss and Jacob Davis in 1873,jeans were first designed as work wear for laborers on the farms and mines of America’s Western states in the late 19^th century. They proved extremely comfortable and durable（耐用的）and were soon in high demand.
[4]But the first explosion of jeans into world of casual-wear had more to do with what jeans had come to symbolize.
[5]When they did start to be worn as casual wear, jeans became a symbol of rebellion—the spirit captured by Marion Brando in his 1953 film The Wild One and by James two years later in Rebel Without a Cause.
[6]Many teenagers in 1953 wanted to be Marlon Brando, and Hollywood costume designers put all the bad boys in jeans. Jeans were soon banned in schools from coast to coast which only added to the passion with which teenagers loved them.
[7]But jeans’ popularity kept growing also because they put different classes on a level playing field. They were affordable and hard-wearing, looked good worn as well as new, and didn’t have to be washed often or ironed at all. They suited to the body in a way that matched even the most finely tailored clothes. This became especially important for women because then, and now, they paid more attention to fit. This versatility（多用途）,the ability to become all things to all people ,is the secret to jeans’ survival as a closet item.
