"White robe" in the ancient Egyptian language known as Coptic

priestly vestment common to all ranks of the clergy from the Deacon to Patriarch; a full-length chiton with sleeves, worn under all other vestments.

The Sticharion (also Stikharion or Stichar; Greek: στιχάριον; Slavonic: стихаръ) is a liturgical vestment of the Eastern Orthodox Church, roughly analogous in function to the alb of the Western Church. It is a long, narrow robe with loose sleeves, fastened at the neck, and often open down the sides but held shut with buttons. Thus in form, it is close to the dalmatic and tunicle of the Western Church.
