Undergarment

Undergarment refers to clothing worn beneath outer garments. The category includes underwear such as briefs, boxers, panties, and bras; as well as undershirts and camisoles, slips, shapewear, and lingerie. Hosiery such as stockings and tights is commonly worn under clothes. Undergarments are designed to provide support, warmth, moisture management, modesty, or shaping, often in combination with outerwear.

Historically, undergarments have varied with fashion and technology. Early garments were simple wraps and loincloths. In the 18th and 19th centuries, corsets shaped the torso and, at times, restricted movement. The 20th century brought modern bras, standardized underwear, and more comfortable fabrics, reflecting evolving social norms, work environments, and athletic wear.

Contemporary undergarments come in diverse styles and fabrics. Materials commonly include cotton for breathability, nylon and polyester for durability and moisture management, silk for luxury, and elastics for stretch. Bras differ by support and cup shape; underwear ranges from briefs to thongs; undershirts vary by weight and sleeve length; shapewear aims to smooth contours.

Proper fit is essential for comfort and function. Sizing systems vary by region and brand. Care instructions emphasize washing according to fabric, avoiding high heat to preserve elasticity, and air drying when possible. Cultural norms influence naming, modesty expectations, and gender labeling. Undergarments form a foundational layer in clothing, supporting hygiene, comfort, and everyday practicality.
