Pajamas or pyjamas (see also spelling differences) is a word with several different, related meanings in the field of
clothing.The original pajamas — are loose, lightweight drawstring trousers tied around the waist and worn in
South and
West Asia.A loose, two-piece garment derived from the preceding garment, is worn as (especially men's and boys')
sleepwear, in
Britain, the
United States, and other countries. Pyjamas in this sense consist of a
jacket and trouser combination, made of a lightweight non-stretch material, similar to materials used in
bed sheets, with the jacket closing down the front with
buttons. These first appeared in Britain as a result of
British colonial presence in
South Asia in the 18th and 19th centuries, and by the early 20th century had replaced
nightshirts as the dominant style of sleepwear for men and boys there. (In South Asia these are known as night suits.)Other garments are derived from the preceding garment, such as women's beach pajamas.In popular culture, the image of a comfortable T-shirt and mens' boxers worn by young women has to be included as a modern pajama style.(Chiefly American) any of a wide variety of (mostly two-piece) sleeping garments are worn by both genders, including the aforementioned jacket and trouser combination, but also including many unrelated styles. In particular, many of these (especially ones for children) are made of stretch knit fabrics of various weights and thicknesses, with
rib-knit trimmings, and tops that are pulled over the head like a
t-shirt. (See also
blanket sleepers, also known as footed pajamas.) Although a distinction is often made between pajamas and non-
bifurcated sleeping garments such as
nightgowns, some speakers in the U.S. include even the latter within the definition of pajamas.
