When he is fully vested for the Divine Liturgy, he wears the epitrachelion over the sticharion and under the zone and the phelonion. If a priest is simply attending a service, he wears no liturgical vestments, but will put on his epitrachelion (and in Slavic traditions, his epimanikia) before receiving the Eucharist."@en .
