What are "stirrup pants"?

Stirrup pants are a type of close-fitting pants that have a stirrup-shaped loop of fabric that fits underneath the arch of the foot, holding the pants securely in place. They were originally designed as sportswear for activities such as horseback riding or skiing, as the stirrup prevented the pants from riding up or bunching at the ankle. Stirrup pants typically have a slim or tapered leg that falls smoothly from the waist to the ankle and are often made from stretchy fabrics such as spandex or lycra for a close, body-hugging fit. While they were initially designed for athletic activities, stirrup pants have become a popular fashion item and can be worn with a variety of tops and shoes for a stylish, streamlined look.
