Pajamas

Pajamas are loose-fitting garments worn for sleeping or lounging. The word originates from Persian and Hindustani forms meaning leg garment, and the modern term entered English through colonial contact in the 18th and 19th centuries. Pajamas commonly refer to a two-piece set consisting of a top and matching trousers, though variations exist in different regions.

Historically, loose trousers paired with a tunic or shirt were traditional attire in parts of the Indian subcontinent. In the 19th century, British colonists adopted similar clothing as sleepwear, later popularizing two-piece pajama sets in Europe and North America. Over time, a one-piece version known as a union suit or sleeper also gained popularity, especially in the United States. Today, pajamas encompass a wide range of styles, from simple cotton sets to luxurious silk or satin ensembles, and include both seasonal options and lounge wear.

Styles and materials vary by climate and culture. Common designs include short- or long-sleeved tops with drawstring or elastic-waist pants, as well as one-piece sleepers for children and adults. Fabrics range from breathable cotton and flannel to satin and synthetic blends, with flame-resistant fabrics used for children's sleepwear in some regions. Care requirements typically include machine washing and air or low-heat drying.

Global use and cultural context differ. In many Western countries, pajamas are primarily sleepwear, while in some regions they are worn as daytime lounge wear. Market trends increasingly blend pajama aesthetics with general loungewear and athleisure.
