What is a strapless bikini?

A strapless bikini is a type of swimsuit that does not have straps around the neck or the back, and instead relies on elastic bands or other forms of support to stay in place. Strapless bikinis are designed to be worn without the need for straps, which allows for a more tan-line-free look and greater freedom of movement. They are often considered to be more revealing and are popular among those who want to show off their shoulders, back, and upper chest. Some strapless bikinis are designed with built-in support, such as underwire cups or padded inserts, to provide additional support and shape to the bust.
