Sirwal

Sirwal, also sherwal, saroual,[1][2] seroual, sarouel or serouel[3] (Arabic: سِرْوَال (sirwāl),[nb 1] also known, in some contexts, as (a subtype of) Harem pants, are a form of trousers.

The word is of Persian origin; shalwār (شلوار) was borrowed into Greek as σαράβαρα sarábāra, "loose trousers worn by Scythians".

[4] They are typically worn in Muslim countries, but also extensively in the Polish Commonwealth, in Mallorca, in the Greek countryside, and other places in the Balkans that were influenced by Ottoman Turks prior to World War I.

The seroual formed part of the standard uniform for the Mameluke[1][2][8] squadrons of Napoleon's Imperial Guard, and for the North African zouave, spahi and tirailleur regiments of the French Army from 1830 to 1962.

The French Army version of the seroual was notable for being cut so widely that it did not require two separate trouser legs.
