Western wear is a category of men's and women's clothing which derives its unique style from the clothes worn in the nineteenth century American West.

Western wear ranges from accurate historical reproductions of pioneer, mountain man, Civil War, cowboy and vaquero clothing to the stylized garments popularized by singing cowboys such as Gene Autry and Roy Rogers the 1940s and '50s.

The most elaborate western wear is the custom work created by rodeo tailors such as Nudie Cohen, which is characterized by elaborate embroidery and rhinestone decoration. (See also Nudie suit.) This type of western wear, popularized by country music performers, is the origin of the phrase Rhinestone Cowboy.
