Cowgirl

While impractical for everyday work, the sidesaddle was a tool that gave women the ability to ride horses in "respectable" public settings instead of being left on foot or confined to horse-drawn vehicles. Following the Civil War, Charles Goodnight modified the traditional English sidesaddle, creating a western-styled design. The traditional charras of Mexico preserve a similar tradition and ride sidesaddles today in charreada exhibitions on both sides of the border.
It wasn't until the advent of Wild West Shows that "cowgirls" came into their own. These adult women were skilled performers, demonstrating riding, expert marksmanship, and trick roping that entertained audiences around the world. Women such as Annie Oakley became household names. By 1900, skirts split for riding astride became popular, and allowed women to compete with the men without scandalizing Victorian Era audiences by wearing men's clothing or, worse yet, bloomers. In the movies that followed from the early 20th century on, cowgirls expanded their roles in the popular culture and movie designers developed attractive clothing suitable for riding Western saddles.
