What are "stretch pants"?

Stretch pants, also known as leggings or jeggings, are a form-fitting type of pants made from stretchy fabrics such as spandex, elastane, or polyester blends that hug the legs and often the waist. Originally worn primarily for exercise or as a form of dancewear, stretch pants have become a popular fashion trend and are now worn for a variety of occasions, including casual and dressy events. They come in a range of styles, colors, and patterns and can be paired with various tops and shoes to create different looks.
