What is a reversible bikini？

A reversible bikini is a type of swimsuit that can be worn with either side facing outward, effectively giving the wearer two suits in one. Reversible bikinis may have different colors or patterns on each side, or they may have a solid color on one side and a pattern on the other. Some reversible bikinis also have different styles or cuts on each side, such as a high-waisted bottom on one side and a low-rise bottom on the other. Reversible bikinis are often a practical choice for people who want to have more versatility in their swimwear, as they can switch between two different looks without having to bring multiple suits on a trip or to the pool.
