Kushti
Kushti (also: Kusti, Koshti) is the sacred girdle worn by Zoroastrians around their waists. Along with the Sedreh, the Kushti is part of the ritual dress of the Zoroastrians.
The Kushti is worn wound three times around the waist. It is tied twice in a double knot in the front and back, the ends of the Kushti hanging on the back. The Kushti is made of 72 fine, white and woolen threads, which represent the 72 chapters of the Yasna, the primary liturgical collection of texts of the Avesta.
