The study of Iranian Apparel culture suggests that women at that time of history have been fully covered. The coating consists of a long, loose dress that has been pulled on the ground. Another shorter dress was also worn on the first long dress. And they also wore a rectangle headscarf too. Therefore, since the centre of Zarathustra mission had been Iran and their coverage of the veiled women were complete, there was no need to determine the quality of traditional dress of the time, and Zarathustra tried to deepen the internal hijab and the same clothing of that time was common.
