Clerical collar: There are a variety of options for daily clerical attire, all involving the use of a clerical collar: Collarino (Tab Collar): This is probably the most common type of shirt and collar among Roman Catholic clergy. It resembles a standard dress shirt, but has a standing black collar that is sewn to accommodate a white cloth or soft plastic insert, leaving a small white square at the base of the throat. Neckband: A collarless shirt (similar to a banded collar shirt) tailored to accommodate a strip of linen or plastic that, when worn over the shirt, creates a standing white collar that rings the neck.
