Liturgical Vestment Colors of the Orthodox Church
The Orthodox clergy wear two kinds of robes, non-liturgical and liturgical. The non-liturgical robes are the ordinary daily clothing of the clergy, worn underneath ‘liturgical robes’. Liturgical robes, or ‘vestments’, are worn during church services.
The non-liturgical robes are called cassocks (Greek rason, Ukrainian pidryasnyk) and outer cassocks (Greek exo-rason, Slavonic riassa). Cassocks are floor-length garments that have long sleeves fitted like shirtsleeves. Outer cassocks are also floor-length garments, but they’re more loosely fitting, with very large sleeves.
