A Sports Bra and Shorts Set is a bra that provides support to the breasts during physical exercise. Sturdier than typical bras, they minimize breast movement and alleviate discomfort. Many women wear sports bras to reduce pain and physical discomfort caused by breast movement during exercise. Some sports bras are designed to be worn as outerwear during exercise such as running. There are also sports bras with extra padding for exercises that involve some kind of trauma to the breasts.

Sports Bra and Shorts set (in American English, also called pantsundies or knickers in British English) are a form of women’s underwear. Panties can be form-fitting or loose.
