Jean or Jeans are trousers often made from denim or dungaree cloth. Often the term “jeans” refers to a particular style of pants, called “blue jeans,” which were invented by Jacob Davis in 1871 and patented by Davis and Levi Strauss on 20 May 1873. Starting in the 1950s, jeans, originally designed for cowboys and miners, became popular among teenagers, especially members of the greaser subculture. Historic brands include Levi’s, Lee, and Wrangler. Jeans come in various fits, including skinny, tapered, slim, straight, boot cut, narrow bottom, low waist, anti-fit, and flare. Owing to their high durability as compared to other common fabrics, “distressed” (visibly aged and worn, but still intact and functional) jean trousers have become increasingly fashionable, making pre-sale “factory distressing” a common feature in commercially-sold jeans. Jeans are now a very popular article of casual dress around the world. They come in many styles and colors. However, blue jeans are particularly identified with US culture, especially the United States Old West.
