The rubrics (regulations) for the type of vestments to be worn vary between the various communions and denominations. In some, clergy are directed to wear special clerical clothing in public at all, most, or some times. This generally consists of a clerical collar, clergy shirt, and (on certain occasions) a cassock. In the case of members of religious orders, non-liturgical wear includes a religious habit. This ordinary wear does not constitute liturgical vestment, but simply acts as a medium of identifying the wearer as a member of the clergy or a religious order.
A distinction is often made between the type of vestment worn for Holy Eucharist or Holy Communion and that worn for other services. Non-Eucharistic vestments are typically referred to as "choir dress" or "choir habit", in the Roman Catholic, Orthodox, and Anglican churches, because they are worn for the chanting of the Daily Office, which, in the West, takes place in the choir rather than the sanctuary. In other traditions, there is no specific name for this attire, although it often takes the form of a Geneva gown worn with or without preaching bands and a stole or preaching scarf.
In the more ancient traditions, each vestment—or at least the stole—will have a cross on it, which the clergy kiss before putting it on. A number of churches also have special vesting prayers which are recited before putting each vestment on, especially the Eucharistic vestments.
