This pair of underwear is modeled after, naturally, women's bikini bottoms. The waistband sits a full three inches below the natural waist and has very high-cut leg holes. They also come in string bikini form, in which the leg holes are constructed with a thin string of fabric. The front and back of the string bikini look like triangles.
When to wear them: Because they provide little coverage, they are less visible underneath clothes and thus can be worn under most anything.
