All females over the age of nine must wear a hijab, the Islamic dress. There is no uniformity, however, regarding its type and the amount of coverage it provides. The black chador (the loose head-to-toe covering) isn’t compulsory. the most common wear is manto , a full-length, usually long-sleeved overcoat, an overwhelming array of which is readily available in the shops. If you don’t want to buy any, bring a knee-length, loose tunic that can be worn with a long skirt or trousers (jeans are acceptable). Hair must be covered with a scarf. The colors of the clothes do not really matter. If you travel in summer, light fabrics and sandals are strongly recommended.
There are few restrictions about men’s dress. Only shorts, even knee-length, are unacceptable. Shirts with short sleeves are fine. It is not mandatory for women to wear a Chador in public places unless intending to visit sites of a holy Shrine. It is however enforced for women to wear a long sleeve shirt and pants or long skirts. (There is no limitation on the color or material).
