Zoroastrians were subjected to public discrimination through dress regulations – not allowed to wear new or white clothes, and compelled by enactments to wear the dull yellow raiment already alluded to as a distinguishing badge. They were not allowed to wear overcoats but were compelled to wear long robes called "qaba" and cotton "geeveh" on their feet even in winter. Wearing eyeglasses, long cloak, trousers, hat, boots, socks, winding their turbans tightly and neatly, carrying watch or a ring, were all forbidden to Zoroastrians. During the rainy days they were not allowed carry umbrellas or to appear in public, because the water that had run down through their bodies and cloths could pollute the Muslims. Zoroastrian men in Yazd would carry a large shawl that they would place under their feet when visiting a Muslim's home so as to prevent the carpet from being polluted. Forbidden from riding horses and only allowed to ride mules or donkeys, upon facing a Muslim they had to dismount. Not until 1923, was the general proscription against Zoroastrians' riding horses and donkeys lifted by Reza Shah.
