Tunicle
Gernerally now adays there is very little difference between the tunicle and the dalmatic. Originally they were distinct items, but by the 17th century the two became identical, though a tunicle is often less ornamented than a dalmatic, the main difference often being only one horizontal stripe on a tunicle versus the two on a dalmatic.
Today, the tunicle is rare in the Roman Catholic Church as only certain authorized clerical societies (such as the Priestly Fraternity of St. Peter) have subdeacons. In the Anglican Communion the tunicle is still used in High Church parishes and cathedrals by the person acting as the Sub-Deacon of the Mass. This may be a Priest, Deacon or a suitable authorised lay person such as a Reader. In addition some churches following English Use rites tunicles are worn by crucifers and other servers.
