Jeans are a type of pants or trousers made from denim or dungaree cloth. Often the term "jeans" refers to a particular style of trousers, called "blue jeans", with the addition of copper pocket rivets added by Jacob W. Davis in 1871 and patented by Davis and Levi Strauss on May 20, 1873. Prior to the patent, the term "blue jeans" had been long in use for various garments, constructed from blue-colored denim.

Trousers, slacks, or pants are an item of clothing worn from the waist to anywhere between the knees and the ankles, covering both legs separately. In the United Kingdom, the word pants generally means underwear and not trousers. Shorts are similar to trousers, but with legs that come down only to around the area of the knee, higher or lower depending on the style of the garment. To distinguish them from shorts, trousers may be called "long trousers" in certain contexts such as school uniform, where tailored shorts may be called "short trousers" in the UK.
