Iran before the revolution

Dress conservatively

That means no shorts for men, but short-sleeves are ok. Although the rules for Islamic hijab also apply to female tourists, they are more lax. A tunic or long shirt that covers your bum and a lightly draped headscarf will suffice. Pants should not go above ankle-length, and sandals with no socks are fine. All colors are welcome, and Iranian women, who are very fashion-conscious, wear especially colorful outfits in the spring and summer.
