Underwear, also known as underclothing or undergarments, refers to items of clothing worn beneath outer clothes, usually in direct contact with the skin. They serve various purposes such as providing an additional layer of clothing in cold climates, preserving modesty, and in some cases, serving as nightwear or swimwear. Underwear can also be designed for sexual attraction or visual appeal. Historically, underwear was predominantly unseen in public, but in the 1950s, it began to be promoted as a fashion item in its own right, leading to the use of prints and colors. Mens underwear has historically served multiple purposes, including protection, modesty, adornment, and support, as well as for sexual or erotic purposes. The materiality of mens underwear is crucial, as it provides a protective layer between the body and outer garments, and also addresses cultural discomfort associated with nudity or nakedness.
In summary, underwear is a fundamental part of clothing worn next to the skin under other clothes, with a rich history and various functions beyond mere coverage.
