Tonsured monastics always wear a klobuk in church and the refectory and whenever else formally dressed. During the services, there are specified times when monks are to remove the klobuk and lay it on their left shoulder to denote reverence for the sacred (for instance, when the Priest brings the Chalice out through the Holy Doors for the distribution of Holy Communion during the Divine Liturgy). Nuns do not normally remove the klobuk at any time during services.[3]
