Western wear is a category of men's and women's clothing which derives its unique style from the clothes worn in the 19th century Wild West. It ranges from accurate historical reproductions of American frontier clothing, to the stylized garments popularized by Western film and television or singing cowboys such as Gene Autry and Roy Rogers in the 1940s and 1950s. It continues to be a fashion choice in the West and Southwestern United States, as well as people associated with country music or Western lifestyles, for example the various Western or Regional Mexican music styles. Western wear typically incorporates one or more of the following: Western shirts with pearl snap fasteners and vaquero design accents, blue jeans, cowboy hat, a leather belt, and cowboy boots.

The Western is a genre of fiction typically set in the American frontier between the California Gold Rush of 1849 and the closing of the frontier in 1890, and commonly associated with folk tales of the Western United States, particularly the Southwestern United States, as well as Northern Mexico and Western Canada.
