- Women judged to be dressed immodestly will also be refused entry.
- The wearing of headscarves is obligatory in public.
- In Tehran, lightweight clothing is worn from April to October while medium weights are advised from November to March.
- The most common uniform consists of a head scarf (roo-sari) to conceal the head, a formless, knee-length coat known as a Mmaanto and a dress or pair of pants. In holy sites, you may be expected to dress more modestly in a chādor, a cloth to cover you.
- As a foreigner, a female traveler is officially expected to cover her hair. Usually, more tolerance tends to be shown towards foreigners over the detail of the dress code than is the case for Iranian women. However, this does not include leaving one’s hair fully uncovered. “Acceptable” outfits may include a, loose dress or shirt worn over loose skirt or pants and a scarf in the summer, and a woolen coat and scarf in the winter (calf-length is acceptable if worn over pants). All colors and modest designs are acceptable.
- Men are also required to abide by the following dress code: Short-sleeved shirts and t-shirts are acceptable for daily wear. Shorts and three-quarter length pants are acceptable on the beach. Dress attire for men is similar to that in Europe. It is quite acceptable in the areas outside though it denotes indifference toward or opposition against state regulations and values. Jogging in tracksuits is acceptable for men.
- Some mosques and most holy shrines require women to be wearing a chādor before entering the complex. If you don’t have one, there are sometimes kiosks by the door that lend or hire chādors. It is better for men to wear long-sleeved shirts inside a mosque or shrine, though this is not mandatory. Shoes are not worn within prayer areas of a mosque or shrine. Busier mosques have free shoe repositories where you trade your shoes for a token.
- Holy shrines, like those in Mashad and Qom, are usually off limits to non-Muslims, although the surrounding complexes are fine. Always ask first before you enter a room you are unsure of. Also, note that the Islamic dress codes still apply even to non-Muslims.
