A bikini is a two-piece swimsuit designed for women, typically consisting of a top that covers the breasts and a bottom that covers the groin area. It is often made from materials like nylon or spandex, which are lightweight and quick-drying. Bikinis come in various styles, colors, and patterns, allowing for personal expression and fashion choices. The bikini was introduced in 1946 by French designer Louis Réard and gained popularity in the 1960s, partly due to its association with beach culture and the swimwear industry. Today, bikinis are commonly worn at beaches, pools, and resorts around the world.
