Jeans are a very popular type of pants that originated in the American West in the 19th century, originally as cargo pants used by miners and cowboys. They were invented by Levi Strauss in 1849 and were first known as "denim pants." Jeans are usually made of indigo denim, which is popular for its wear-resistant and dirt-resistant properties. The design of jeans is diverse, including high waist, low waist, straight tube, tight, wide legs, holes and other styles, which can meet the needs of different people. In terms of fabric, in addition to traditional denim, there are a variety of options such as suede, corduroy, velvety and so on. In recent years, the introduction of Lycel tencel fabric has brought new possibilities for jeans, which are lighter and softer than traditional denim, breathable and comfortable, especially for summer wear.
