pajama

Pajama, also spelled pyjama in some regions, is a loose-fitting garment or set worn for sleep or lounging. A typical two-piece version consists of a shirt or blouse-style top and matching trousers, though one-piece variants exist. The term derives from the Persian or Urdu pajāmeh (payjama), meaning leg garment, and entered English in the 19th century during British colonial rule in India. Spelling varies by region: pajama(s) in American English; pyjama(s) in British and many Commonwealth varieties.

History and use: Pajamas originated in South Asia as comfortable nightwear suited to warm climates and ease of movement. British soldiers and administrators encountered and popularized the style in the 1800s, contributing to its adoption in Western fashion. Since the mid-20th century, pajamas have become standard sleepwear worldwide, produced in a wide range of fabrics and designs.

Design and materials: Modern pajamas are commonly made from cotton, flannel, or blends, with silk or satin used for luxury sets. They range from lightweight summer styles to insulated winter versions. Closures include buttons or elastic waistbands, and waist construction may be drawstring or elastic. Patterns and colors vary from solids to prints.

Variants and cultural notes: One-piece pajama designs, sometimes called pajama suits or onesies, are worn for lounging or sleep. Pajamas come in gendered and children's styles, and pajama-inspired designs have influenced contemporary fashion, including loungewear and streetwear trends. In many cultures, pajamas are primarily worn at home for comfort and sleep, though public usage varies by social norms.

Care: Cotton and blends are usually machine washable; silk or satin sets require special care per label instructions.
