For men this means eschewing tight pants, shorts, short-sleeved shirts, and open collars. This precludes women from some physically active professions. In earlier years, Revolutionary guards accosted women who violated the dress codes in public, including wearing makeup, but today these attacks are rare. For many centuries women in Iran have worn the chador, a semi-circular piece of dark cloth wrapped expertly around the body and head, and gathered at the chin. In adopting this dress, women have been wonderfully inventive.
Women wear it over jeans or other Western fashions.
In short, Iranian women have created high fashion from their concealing garments. Many older, westernized women decry any restrictions on their dress, but younger women who grew up in the Islamic Republic take it in stride. I'm far more concerned about press restrictions than about dress codes. Indeed, the code may have helped women from conservative families. Now they have no trouble letting their daughters go anywhere.
