Often referred to as high-cut panties, these gained a resurgence in the 1980s, thanks to Jane Fonda's exercise videos. They have the same high waist as the classic brief, but it features high-cut leg holes that rise just above the widest part of the thigh, which is often better for circulation.
When to wear them: If you are Miley Cyrus. Or if you want the coverage of a brief but find the elastic band around the leg uncomfortable.
