Lingerie has evolved significantly since ancient Egypt. The term originated from the French word for linen. In the 1500s, Catherine de' Medici introduced the first true corset. Corset designs became less constricting in the 1800s as elastic corsets and the hourglass silhouette emerged. In the early 1900s, the first brassiere was created and styles continued to change through the decades, including the popularity of camiknickers in the 1920s, Christian Dior's New Look in the 1940s, and the rise of risqué styles in the 1950s. Surveys now show the global lingerie market is worth billions.
