A zoster (Greek: ζωστήρ, zōstēr) was a form of girdle or belt worn by men and perhaps later by women in ancient Greece, from the Archaic period (c. 750 – c. 500 BC) to the Hellenistic period (323–30 BC).
The word occurs in Homer, where it appears to refer to a warrior's belt of leather, possibly covered in bronze plates. Later references in the late Archaic and early Classical periods show it used as a belt or cloth girdle with men's clothes, especially the shorter chiton.
The zoster was also worn and is still worn by Greeks when wearing traditional costumes (regional clothing).
