Kalimavkion

• In the Greek tradition, monks wear a simple black kalimavkion, covered by a black veil, but ordained clergy wear a kalimavkion with a flattened conical brim at the top. Hierodeacons remove the veil when they vest for services, but hieromonks do not. In the Greek tradition, nuns do not normally wear a kalimavkion, but rather just the veil.
• In the Russian tradition, priests and deacons, if awarded it, wear a kamilavka that is normally taller than the Greek style, widens as it rises, and is flat at the top. Monks wear a black kamilavka with black veil. Russian nuns also wear the kamilavka with veil. Hieromonks and hierodeacons wear the same black kamilavka and veil as non-ordained monastics. Again, hierodeacons remove the veil when they are serving, but hieromonks do not. Protodeacons are awarded a purple or red kamilavka, but Archdeacons continue to wear the black kamilavka. Archpriests are also awarded a purple or red kamilavka. Bishops, who are always monks, wear a black kamilavka with a black veil. Archbishops are distinguished by a jewelled cross on the front of their veil. Metropolitans wear a white veil over their kamilavka, with the same cross as an archbishop. The Patriarch of Moscow instead of the kamilavka wears a white koukoulion, a conical head covering with a monastic veil.
• In the Serbian Orthodox Church clergy of all ranks wear a black kalimavkion which is flat at the top. Monastics wear a black veil over the kalimavkion during services. Bishops wear a black kalimavkion with a wide purple band at the bottom, and remove the veil when they are outside the church.
• Syriac Catholic Priests and bishops in the past have worn a kalimavkion. However this practice has faded to only a few wearing it and has almost explicitly been used by the patriarch only.
