What is a "leg warmer"?

A leg warmer is a long, tubular garment that is designed to cover the legs, typically from the ankle to just below the knee. They are usually made of knitted wool, acrylic, or other synthetic fibers, and are often worn by dancers, athletes, or people engaging in other physical activities to keep their legs warm during exercise. Leg warmers became popular in the 1980s as a fashion accessory, and were often worn over leggings or tights. Today, they continue to be worn by dancers, fitness enthusiasts, and people looking to add stylish accessories to their outfits.
