over a sleeveless cassock or a non-cuffed gown over an Anglican or Roman style cassock. The American Geneva gown is often supplied with a cuff sewn into the double-bell sleeve (this innovation is a remnant of the cassock sleeve that was formerly worn underneath). As is the practice in the Anglican churches, cassocks may be worn by others who are not ministers. Ordained elders and deacons, as they serve as worship leaders, readers, and administer communion may also wear cassocks which tend to be black. Those worn by choirs and other worship leaders are usually coloured (for instance, The Shadyside Presbyterian Church (U.S.A.) choir is dressed in red cassocks under white surplices). Eastern Christian practice In Eastern Christianity there are two types of cassock: the Inner Cassock and the Outer Cassock or Rason. Monastics always wear a black cassock. There is no rule about colouration for non-monastic clergy, but black is the most common. Blue or grey are also seen frequently, while white is sometimes worn for Pascha.

The Greek version, called an anteri (αντερί), rason (ράσον), or zostiko (ζωστικό) is somewhat fuller, gathered at the waist with a narrow cloth belt, and with a high collar buttoned in the front. The inner cassock is usually worn by all clergy members under their liturgical vestments. The outer cassock ( , , ) is a voluminous garment worn over the inner cassock by bishops, priests, deacons, and monastics as their regular outerwear. It is not worn by seminarians, readers or subdeacons in the Russian tradition. In the Greek tradition, however, chanters may wear it in church, usually with no inner cassock beneath but directly over secular clothing. The outer cassock should be worn by a priest celebrating a service such as Vespers where the rubrics call for him to be less than
