Dress under Iranian law, women wear the hijab. However, the Iranian hijab is significantly different from what is used in some countries and is diverse and colorful. Any kind of cover that is not so thin and covers the arms, legs and hair is considered an example of Iranian hijab and there are no restrictions in terms of choosing the color and design of the dress. This level of hijab is enough for tourism in Iran. In other words, the hijab is not dealt with in an extreme way in Iran, and you will find out by looking at the clothing of Iranian citizens.
Under Iranian law, it is not common for men to wear sleeveless blouses and trousers that are too short, although not prohibited by law, in public. It is necessary for women tourists in Iran to cover some of their hair. It is better for women tourists to have a scarf or shawl in their handbag to respect the culture of their host community so that they do not have any problems preparing it at the airport. If you do not have a scarf with you, nothing special will happen except to spend a little time and money to buy it from the store.
Iranian Law on Visiting Religious Attractions
According to Iranian regulations, female tourists must use a special cover called “chador” to visit some of Iran’s religious attractions (Imam Reza shrine in Mashhad, Hazrat Masoumeh shrine in Qom, Shahcheragh shrine in Shiraz, etc.). In these attractions, tents are provided to visitors for free. The Iranian tent consists of a large and patterned piece of cloth that is placed on the head. The use of this cover is rooted in cultural and religious beliefs and is considered a kind of respect for that attraction. Male tourists do not need to use tents. However, they should use the usual clothing of Iranian men (shirts and pants)(dress).
