An izaar , futah ), ma'awaz , wizara , magtab or maqtab is a lower garment typically worn by men in the United Arab Emirates, Somalia, Indonesia, Oman, Yemen, Djibouti, Eritrea, Saudi Arabia, Qatar, Malaysia, India, Bahrain, Bangladesh, Pakistan and some parts of East Africa. It is also commonly worn by some other Arabs at home. In some parts of Arabia ( Yemen, and Jizan and ĘżAsir Regions of Saudi Arabia), it is called "futah" instead of izaar. Some of these may feature tassels.
In India and Bangladesh it is known as Lungi and in Somalia and Djibouti it is known as "macawis". A similar garment made from Batik loom material is called Sarong and is used by ethnic Malays and also in Sri Lanka.
It is similar to a kilt, except it is lighter and thinner. It is usually striped or patterned with bold colours (often with rectangular shapes), but it can also be found plain. An izaar is usually folded around the lower body, then wrapped tightly around the waist.
