Young Teen Girl In Tight Pants

In most of the Western world, trousers have been worn since ancient times and throughout the Medieval period, becoming the most common form of lower body clothing for males in the modern period, although shorts are also widely worn, and kilts and other garments may be worn in various regions and cultures. Since the 20th century, trousers have become prevalent for females as well. Shorts are often preferred in hot weather or for some sports, and also often by children. Trousers are worn at the hips or waist, and may be held up by their own fastenings, a belt, or suspenders (braces). Leggings are form-fitting trousers of a clingy material, often knitted cotton and spandex.
