What is a bikini sarong?

A bikini sarong is a garment that is worn around the waist and can be used to cover up a swimsuit, particularly a bikini. It is usually made of lightweight fabric, such as cotton or rayon, and is worn like a skirt. Some bikini sarongs are designed to be worn wrapped around the waist, while others have ties or other fastenings that allow them to be secured in place. They are often worn as a cover-up over a swimsuit at the beach or pool, but can also be worn as a casual skirt in other settings.
