A string bikini is a type of swimwear characterized by its minimal coverage and thin straps. It typically consists of two triangular pieces of fabric for the top and a small bottom piece that is held in place by strings on the sides. This design allows for a more revealing look, making it popular for sunbathing and beach activities. String bikinis come in various styles, colors, and patterns, catering to different fashion preferences. They are often made from materials like nylon or spandex, which provide comfort and flexibility. Many people choose string bikinis for their ability to create a tan line that is less noticeable than that of traditional swimsuits.
