Trousers
From AmtWiki
Trousers, often called pants, are an item of clothing worn on the bottom half of the body, with materials covering both legs separately. They usually extend from waist to ankle, though trousers that are higher than ankle-high are often given a different name.
History of Pants
Trousers have been theorized to have been invented to aid horseback riding, and pairs have been found that are as old as 13th century B.C. in China.
In the West, trousers have been the standard lower-body clothing item for males since the 16th century; by the late 20th century, they had become prevalent for females as well. Trousers are worn at the hips or waist, and may be held up by their own fastenings, a belt, or suspenders.
