Clerical collar

A clerical collar is an item of Christian clerical clothing. It is a detachable collar that buttons onto a clergy shirt or rabbat (vest), being fastened by two metal studs, one attached at the front and one at the back to hold the collar to the shirt. The collar closes at the back of the neck, presenting a seamless front. It is almost always white and was originally made of cotton or linen but is now frequently made of plastic. Sometimes it is attached with a "collaret" or "collarino" that covers the white collar almost completely, except for the top edge and a small white square at the base of the throat, to mimic the collar of a cassock. The clerical shirt is usually black (or another color appropriate to a person's ministry rank), with a detachable tab of white in the front. When clergy are delivering sermons, they sometimes attach preaching bands to their clerical collar.
