JEANS

We all uses jeans. Jeans are trousers made from denim or other materials such as corduroy.Dry goods merchant Levi Strauss was selling blue jeans under the "Levi's" brand to the mining communities of California in the 1850s. One of Strauss' customers was Jacob Davis, a tailor who frequently purchased bolts of cloth from the Levi Strauss & Co. wholesale house. After one of Davis' customers kept buying cloth to reinforce torn pants, he had an idea to use copper rivets to reinforce the points of strain, such as on the pocket corners and at the top of the button fly. Davis did not have the required money to purchase a patent, so he wrote to Strauss suggesting that they both go into business together. After Strauss accepted Davis's offer, the two men received U.S. Patent 139,121, for an "Improvement in Fastening Pocket-Openings," on May 20, 1873. Jeans are very useful and convenient , especially when we participate in outdoor activities because they are hard to wear out.In 1885, jeans could be bought in the US for $1.50 (approximately $36 in 2010). Today in America, a pair of durable jeans can be purchased in the United States for about 40 dollars. Americans spent more than $14 billion on jeans in 2004 and $15 billion in 2005.
