Iranian women against islamic outfit

Perhaps the most visible mark of Iran's Islamic leanings is the conservative dress expected of its citizens. Although normal, Western style clothing is acceptable in private homes, when in public women are required to cover everything but their face, hands and feet.
The most common uniform consists of a head scarf (roo-sari, to conceal the head and neck, a formless, knee-length coat known as a roo-poosh and a long dress or pair of pants. In and around holy sites, you will be expected to dress even more modestly in a chādor, a full-length swathe of black cloth designed to cloak everything but your face from view.
The dress code can be daunting during your preparation, but roo-saris, roo-pooshes and chādors can be bought chea ply in Iran. Watch or ask friendly Iranian women for guidance and marvel at how young women are pushing the boundaries of modesty with colourful head scarves that cover only a fraction of their hair and figure-hugging roo-pooshes that reveal every curve of their bodies.
Men have a slightly easier time of things. Short-sleeved shirts and t-shirts are acceptable for daily wear. Shorts and three-quarter length pants are only acceptable on the beach.
Although no trip to Iran would be complete without a glimpse at the stunning architecture and sombre environments of its mosques or holy shrines, many travellers are daunted by the prospect of walking into the foreign world of a mosque. Don't let these fears stop you, Iranians are welcoming and will understand any unintended breach of protocol.
