Sarongs known under a variety of local names are traditionally worn by the people of Yemen and elsewhere on the Arabian Peninsula. Local names for the garment include fūṭah, izaar, wizār and maʿwaz (pl. maʿāwiz). In Hadhramawt sarong is called ṣārūn in the interior and ṣārūm in the coastal region. In Oman, sarongs are called wizār and are often white in color, similar to the Keralan mundu of the Indian subcontinent and it is usually worn under the Thawb. In Saudi Arabia, sarongs are known as izaar. Designs can be checkered or striped as well floral or arabesque, but double plaid (i.e., a vertical section of the izār with a different plaid pattern) designs from Indonesia are also very popular. In southwestern Saudi Arabia, tribal groups have their own style of unstitched izaar, which is locally woven. This is also worn in northern Yemen. However, the tribal groups in Yemen each have their own design for their fūṭah, the latter of which may include tassels and fringes. It is thought that these tribal futah resemble the original izaar as worn on the Arabian Peninsula since pre-Islamic times such as the Shendyt. They are generally worn open and unstitched in such a way that the garment does not reach over one's ankles. Other izaars, often imported from Bangladesh, are the traditional clothing of Arab fishermen of the Persian Gulf, the Indian Ocean and the Red Sea. It was the traditional garment for men before the introduction of pant-like pajamas and kaftans during the Turkish and European colonial periods. Tube-stitched, as well as open sarongs, are both worn, even in formal dishdasha-wearing countries, as casual sleepwear and at home.
