'''Pajamas''' (American English) or '''pyjamas''' (Commonwealth English),{{efn|Pronounced variously as {{IPAc-en|p|ə|ˈ|dʒ|ɑː|m|ə|z|,_|p|ɪ|-|,_|-|ˈ|dʒ|æ|-}} {{respell|pə|JAH|məz|,_|pih|-|,_|-|JAM|əz}}.}} sometimes colloquially shortened to '''PJs''',<ref>{{Cite web | url=https://www.dictionary.com/browse/pjs | title=PJs | publisher=Dictionary.com}}</ref> '''jammies''',<ref>{{Cite web | url=https://www.dictionary.com/browse/jammies | title=Jammies | publisher=Dictionary.com}}</ref> '''jim-jams''', or in South Asia, '''night suits''', are several related types of clothing worn as nightwear or while lounging. Pajamas are soft garments derived from the Indian and Iranian bottom-wear, the ''pyjamas'', which were adopted in the Western world as nightwear.
==Etymology==
According to the ''Oxford English Dictionary'', the word pyjama is a borrowing via Hindustani from Persian. Its etymology is: <blockquote>Urdu pāy-jāma, pā-jāma and its etymon Persian pāy-jāma, pā-jāma, singular noun < Persian pāy, pā foot, leg + jāma clothing, garment (see jama n.1) + English -s, plural ending, after drawers.<ref name=oed-pyjamas>{{citation|title=Oxford English Dictionary|chapter=pyjamas or pajamas, n.|publisher=OED Online|edition=3|year=2022|url= https://www.oed.com/view/Entry/155351?redirectedFrom=pajamas|access-date=2 May 2022}}</ref></blockquote>
OED's earliest evidence for '''pyjamas''' is from 1801, in the [https://en.wikipedia.org/wiki/The_Asiatic_Journal_and_Monthly_Register_for_British_India_and_Its_Dependencies|The Asiatic Journal and Monthly Register for British India and Its Dependencies] 1800.
==History== thumb|US government advert during World War II, female nightwear The worldwide use of pyjamas (the word and the clothing) outside the Indian subcontinent is the result of adoption by British colonists and soldiers in the Indian subcontinent in the 18th and 19th centuries, and the British influence on the wider Western world during the Victorian era. Pyjamas had been introduced to England as "lounging attire" as early as the seventeenth century, then known as ''mogul's breeches'' (Beaumont and Fletcher) but they soon fell out of fashion. The word ''pyjama'' (as '' pai jamahs,'' ''Paee-jams'' and variants) is recorded in English use in the first half of the nineteenth century. They did not become a fashion in Britain and the Western world as sleeping attire for men until the Victorian period, from about 1870.<ref>Lewis, Ivor. 1991. ''Sahibs, Nabobs and Boxwallahs: A Dictionary of Words of Anglo-India.'' Oxford: Oxford University Press. 266 pages. {{ISBN|0-19-564223-6}}. "They were introduced in England as lounging attire in the 17th century but soon went out of fashion.

''Hobson-Jobson: A Glossary of Colloquial Anglo-Indian Words and Phrases'' (1886) summarizes the state of usage at the time (s.v. "pyjammas"): <blockquote>Such a garment is used by various persons in India ''e.g.'' by women of various classes, by Sikh men, and most by Mohammedans of both sexes. It was adopted from the Mohammedans by Europeans as an article of ''dishabille'' [highly casual clothing] and of night attire, and is synonymous with Long Drawers, Shulwaurs, and Mogul-Breeches [...] It is probable that we English took the habit like a good many others from the Portuguese. Thus Pyrard (c. 1521) <!--serving as apothecary in the Portuguese royal hospital in Goa--> says, in speaking of Goa Hospital: "''Ils ont force ''caleçon'' sans quoy ne couchent iamais les Portugais des Indes''" [fr., "They have plenty of the undergarments without which the Portuguese in India never sleep"] [...] The word is now used in London shops. A friend furnishes the following reminiscence: "The late Mr. B—, tailor in Jermyn Street, some on 12 years ago, in reply to a question why pyjammas had feet sewn on to them (as was sometimes the case with those furnished by London outfitters) answered: "I believe, Sir, it is because of the White Ants."<ref>{{Cite book | last1=Yule | first1=Henry | first2=A.C. | last2=Burnell | title=Hobson-Jobson: A Glossary of Colloquial Anglo-Indian Words and Phrases | year=1886 | url=https://books.google.com/books?id=6Z5iAAAAMAAJ&pg=PA748 | page=748 |quote=''Hobson-Jobson'' glosses "white ants" as "The insect (''Termes bellicosus'' of naturalists) not properly an ant, of whose destructive powers there are in India so many disagreeable experiences, and so many marvellous stories.}}</ref></blockquote><!--Hobson-Jobson cites spelling as ''Paee-jams'' (1828), and ''pyjama'' (1881).-->
==Types==
===Traditional=== [[File:Utility Underwear- Clothing Restrictions on the British Home Front, 1943 D13099.jpg|thumb|British Utility Underwear Clothing Restrictions on the British Home Front, 1942. 11 year old girl wearing wool pajamas as nightwear.]] ''Traditional pajamas'' consist of a shirt-and-trousers combination made of soft fabric, such as flannel or lightweight silk. The shirt element usually has a placket front and sleeves with no cuffs.
Pajamas are usually worn as nightwear with bare feet, and can be worn with or without undergarments.<ref>{{Cite news |last=Borresen |first=Kelsey |date=2 May 2023 |title=Should You Sleep In Underwear Or Go Commando?

===Contemporary=== thumb|370x370px|Pajamas with a drop seat Contemporary pajamas are derived from traditional pajamas. There are many variations in style such as short sleeve pajamas, pajama bottoms of varying length,<ref>[https://web.archive.org/web/20190717204546/https://pijamasdeanimales.com/pijamas-antiguos/ "Harriet Traynham (R) and her guests still wearing their pyjamas at 3:15 pm,"] ''Life'' magazine, August 1951 (Photographer: Lisa Larsen)</ref> and pajamas incorporating various non-traditional materials. Often, people of both sexes opt to sleep or lounge in just pajama pants, usually with a t-shirt. For this reason, pajama pants are often sold as separates. Stretch-knit sleep apparel with rib-knit trimmings are common, mostly with young children.
Although pajamas are usually distinguished from one-piece sleeping garments such as nightgowns, in the US, they have sometimes included the latter or a somewhat shorter nightshirt as a top. Some pajamas, especially those designed for infants and toddlers, feature a ''drop seat'' (also known as a ''trap door'' or ''butt flap''): a buttoned opening in the seat, designed to allow the wearer conveniently to use a toilet.
== Fire safety == In the United States, pajamas for children are required to comply with fire safety regulations. If made of flammable fabric, such as cotton, they must be tight fitting. Loose-fitting pajamas must be treated with a fire retardant.<ref>{{Cite web | url=https://www.cpsc.gov/Business--Manufacturing/Business-Education/Business-Guidance/Childrens-Sleepwear-Regulations | title=Children's Sleepwear Regulations | work=U.S. Consumer Product Safety Commission | date=July 16, 2016}}</ref> Regulations in the United Kingdom are less stringent; pajamas which do not comply with fire safety standards may be sold, but must be labelled "KEEP AWAY FROM FIRE".<ref>{{Cite web | url=https://www.safekids.co.uk/clothesfireflammability.html | title=Children's Clothes and Fire Safety | website=www.safekids.co.uk | first=Danise | last=Tyler | date=May 27, 2011 | access-date=February 11, 2022 | archive-date=February 11, 2022 | archive-url=https://web.archive.org/web/20220211044937/https://www.safekids.co.uk/clothesfireflammability.html | url-status=dead }}</ref>
==Society and culture== [[File:Pajamas on Sunday.jpg|thumb|People wearing pajamas on Wilshire Boulevard, Los Angeles, on a Sunday morning|right|225 px]] Pajamas in the Western world have been regarded as essentially indoors wear, or wear for the home, whether treated as daywear or nightwear.
A 2016 article in the Phoenix ''New Times'' relates that "When the actress Bette Davis turned up in her 1942 [''sic''] film ''Old Acquaintance'' sporting her beau’s pajama top as a nightie, it caused a fashion revolution: I. Magnin clothing buyer Bertie Strausser told ''The New York Times'' that she sold out of men’s sleepwear the morning after the movie opened, and all of it to young women."<ref>{{Cite news | url=https://www.phoenixnewtimes.com/arts/stop-wearing-pajamas-in-public-now-8052621 | title=Stop Wearing Pajamas in Public — Now | first=ROBRT L. | last=PELA | work=Phoenix New Times | date=February 15, 2016}}</ref>
