Underkläder

Underkläder, literally “under garments” in Swedish, is the broad term for garments worn next to or close to the skin beneath outer clothing. The category includes garments for all genders and ages, with aims of comfort, support, hygiene, warmth, and modesty.

Common types cover everyday underwear such as briefs, boxers, and undershirts for men; bras, panties, and shapewear for women; and unisex items like undershirts, thermal underwear, and sports underwear.

Materials include cotton for breathability, synthetic blends such as polyester, nylon, elastane for stretch and moisture management, and blends with modal or lyocell. Care instructions typically include washing at appropriate temperatures; many items are machine washable.

Design features vary by purpose: everyday underwear prioritizes comfort and fit; sports underwear uses moisture-wicking fabrics and flat seams to reduce chafing; thermal underwear provides insulation for cold weather, often made of heavier knit fabrics.

History: Underwear has evolved from restrictive garments such as corsets and petticoats in the 19th century to more practical designs in the 20th century, including bras and briefs. In recent decades, emphasis has been on comfort, fit, sustainability, and size inclusivity.

Cultural context: Attitudes toward underkläder differ by country and culture, but the general function remains personal hygiene, warmth, and modesty. In Sweden and many Western countries, underwear is commonly worn daily, with growing attention to comfort, fit, and ethical production.
