A kaftan or caftan (/ˈkæftæn/; Persian: خفتان, khaftān) is a variant of the robe or tunic. Originating in Asia, it has been worn by a number of cultures around the world for thousands of years. In Russian usage, kaftan instead refers to a style of men's long suit with tight sleeves. Though the kaftan is of ancient Mesopotamian (modern-day Iraq) origin, it has been used by many West and Southwest Asian ethnic groups. It may be made of wool, cashmere, silk, or cotton, and may be worn with a sash. Popular during the time of the Ottoman Empire, detailed and elaborately designed garments were given to ambassadors and other important guests at the Topkapı Palace. Variations of the kaftan were inherited by cultures throughout Asia and were worn by individuals in Russia (North Asia, Eastern Europe and formerly Central Asia), Southwest Asia and Northern Africa.
