The worldwide use of pajamas (the word and the clothing) outside the Indian subcontinent is the result of adoption by British colonistsin the Indian subcontinent in the 18th and 19th centuries, and the British influence on the widerWestern world during theVictorian era.Pajamas had been introduced to England as "lounging attire" as early as the seventeenth century, then known asmogul's breeches (Beaumont and Fletcher) but they soon fell out of fashion. The wordpajama (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.[4]

ThusPyrard (c. 1521) says, in speaking ofGoa Hospital: "Ils ont forcecaleçon 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 inJermyn 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 theWhite Ants."[5]
