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 American West. It 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 in the 1940s and 1950s. Western wear can be very informal, with a t-shirt and blue jeans forming a basic ensemble, or it may consist of tailored formal garments with western accents. At minimum, western wear generally incorporates a cowboy hat, a leather belt, and cowboy boots.
In the early days of the Old West it was the bowler hat rather than the slouch hat, centercrease (derived from the army regulation Hardee hat), or sombrero that was the most popular among cowboys as it was less likely to blow out off in the wind. By the 1870s, however, the Stetson had become the most popular cowboy hat due to its use by the Union Cavalry as an alternative to the regulation blue kepi.
Stampede strings were installed to prevent the hat from being blown off when riding at speed. These long strings were usually made from leather or horsehair. Typically, the string was run half-way around the crown of a cowboy hat, and then through a hole on each side with its ends knotted and then secured under the chin or around the back of the head keeping the hat in place in windy conditions or when riding a horse.
