The sirwal, saroual, seroual, sarouel or serouel ( šalvār; sirwāl; , ), also known as punjabi pants, are a form of baggy trousers predating the Christian era. They are typically worn in Muslim countries, but also extensively in the Greek countryside (and other places in the Balkans that were influenced by Ottoman Turks) prior to World War II. The trousers are not originally an Arab garment but were introduced from Persia to Muslim countries. The drawstring allows the sirwal to be worn at either the waist or hip level. Sirwal are worn by men under the thawb, or alone with some sort of loose top.
