Underwear

Underwear is clothing worn next to the body, usually beneath outer garments, for coverage, support, warmth, or hygiene.

Briefs: Close-fitting undergarments that cover the hips and seat, with legs cut high or short. A classic underwear shape prioritizes coverage and support with minimal leg fabric.
Hygiene: Practices and conditions that promote health and cleanliness. Underwear can absorb perspiration and reduce direct contact between outer clothing and bodily secretions.
Loincloth: A simple garment wrapped around or between the legs and fastened at the waist. It is among the earliest known forms of clothing worn beneath or instead of other garments.
Outerwear: Clothing designed to be worn as the visible outer layer of an outfit. Underwear is ordinarily concealed beneath it, though some garments can serve either role.
Boxer shorts: Loose-fitting shorts worn as underwear, typically with an elastic waistband. Their relaxed cut contrasts with close-fitting underwear styles.
Thermal insulation: The reduction of heat transfer between objects or environments. Insulating underwear helps retain body heat in cold conditions.
Corset: A structured garment worn to shape the torso and support the body. Corsets occupied the historical boundary between underwear, support garment, and fashionable outerwear.
Swimwear: Clothing designed to be worn while swimming or engaging in water activities. Swimwear resembles underwear in fit but is constructed for public wear and water exposure.
Bra: A close-fitting garment designed to support or cover the breasts. Bras are a major underwear form shaped around breast support and fit.
Sportswear: Clothing designed for exercise and athletic activity. Performance underwear manages moisture, friction, and support during movement.
