In August 1927 the Iranian government employees were required to replace their Iranian-style hats and turbans with a new hat, designed based on the French military kepi, called Pahlavi. Later, in December 25, 1928, a new law required all Iranian men to wear Pahlavi Hat.
Two years later in March 1929 (1308) the Iranian People were banned from wearing their ethnic costumes. This time they were required to wear Western-style suit in combination with Pahlavi hat. Six years later, in June 1935 the Iranian parliament passed another law that replaced Pahlavi hat with chapeaux and replaced various types of Iranian footwear with European-style leather shoes. The only people exempted from this law were the clergy, defined for the first time in Iranian history as a new category called the “spirituals” (Rowhaniyat). To keep their attire on the clergy needed to receive a government permit.
All laws regulating people’s attire were repealed after the removal of Reza Shah from power by the Allies in 1940.
