Young Black Haired Girl Undresses Her Jeans And Black Bra Near The Window On The Table At Home

The same type of uniform consisting of jeans and chambray tops was issued as prison uniforms in some correctional facilities mainly because of the durability and low-maintenance of denim which was deemed suitable for the rugged manual labor carried out by inmates. A popular example of the use of denim as prison wear can be seen in the film Cool Hand Luke.
Riveted jeans
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.
