Harem pants

[2] The original so-called 'harem pants/skirts' were introduced to Western fashion by designers such as Paul Poiret around 1910, although they themselves were inspired by Middle East styles, and by şalvar (Turkish trousers).

[3][4] The term 'harem pants' subsequently became popular in the West as a generic term for baggy trousers caught in at the ankle that suggest the Turkish style, or similar styles such as bloomers, the South Asian shalwar and patiala salwar; the Bosnian dimije; sirwal (as worn by Zouaves); and the Ukrainian sharovary.

In 1911, the Paris couturier Paul Poiret introduced harem pants as part of his efforts to reinvent and 'liberate' Western female fashion.

[5][6] His "Style Sultane" included the jupe-culotte or harem pant, made with full legs tied in at the ankle.

[4][5] Poiret himself insisted that he designed harem pants for the chic woman to show off "the harmony of her form and all the freedom of her native suppleness.
