Fashion in Iran is divided into several historical periods. The exact date of the emergence of weaving in Iran is not yet known, but it is likely to coincide with the emergence of civilization. Clothing in Iran is mentioned in Persian mythology. Ferdowsi and many historians have considered Keyumars to be the inventor of the use of animals' skin and hair as clothing. Some historians have also mentioned Hushang as the first inventor of the use of living skins as clothing. Ferdowsi considers Tahmuras to be a kind of textile initiator in Iran. There are historical discoveries in northern Iran from about 6,000 BC that refer to wool weaving at the time. Other discoveries in central Iran dating back to 4200 BC have shown that the animals' skin has not been the only clothing worn on the Iranian Plateau since those years. The clothing of ancient Iran took an advanced form, and the fabric and color of clothing became very important at that time. Depending on the social status, eminence, climate of the region and the season, Persian clothing during the Achaemenian period took various forms. The philosophy used in this clothing, in addition to being functional, also had an aesthetic role.
