What is a "swimming costume"?

A swimming costume, also known as a swimsuit, is a garment designed to be worn during swimming and other water-based activities. It typically covers the torso and groin area and can be made of a variety of materials, including nylon, spandex, and polyester. Swimsuits come in different styles and designs, including one-piece and two-piece options, and are available for both men and women. They are designed to be comfortable, flexible, and quick-drying, allowing the wearer to move freely in the water. Swimsuits are also available in a range of sizes and colors, making it easy to find a style that suits individual preferences and body types.
