Having said that ~ If it is so that the āclerical collarā was, in fact not āROMAN CATHOLICā in its origin, but was instead Protestant (which, by the way, is was, ordinary research shows)
Actually, to be more accurate, the ātab shirtā is a protestant invention.
For a pic, the man in the box #811 is wearing a classic ātab shirtā

The actual Roman collar (not to be confused with the tab) differs in structure, but does not look like a white square in a band of black. It is a white collar with a notch in the black part of the cassock (or shirt). Generally speaking, when worn with the cassock or simar, it is a white band of plastic or linen that snaps or buttons together at the back of the neck and it attached to a rabat (pronounced rab-ee). The collar of the cassock generally has a notch at the throat which, combined with the collar and rabat give the proper Roman collar look. The collar can also be worn without any black covering it up, though this has seemingly fallen out of style with Catholic clergy.
There are also different types for certain religious orders, although this practice has kind of fallen out of style recently.
While the Roman collar as we think of it today was a fairly recent addition, it is definately Catholic in origin.
Concerning protestants wearing tab shirts, I really donāt care as itās their business. Furthermore, the collar doesnāt mean āpriestā and never has. Seminarians used to always wear it (and still do depending on the situation), deacons can wear it, etc. Iāve learned not to assume a man in a collar (be it a band, Roman, tab shirt, whatever) is a priest.
The cassock practically screams Catholic, and this why I personally donāt like the tab shirt and prefer a proper Roman cassock (Roman, French-cut Roman, or semi-Jesuit) or at least shirt front rabat (w/ Roman collar) and suit. āTabulatingā (a little bit of seminary slang) seems to result in the unbecoming practice of unbuttoning the top button of the tab shirt and allowing the tab to hang out like a tongue depresser or find its way into the front pocket.
Hereās some pics of men in the rabat vest (which is different from the much smaller cassock rabat) that show the full band collar and the Roman collar. Note also the appropriate use of French cuffs, which used to be kind of an unoffical part of the outfit and are now making a comeback.

As to the importance of this discussion, no it isnāt a central issue but there are important ramifications. Clerical attire of some sort is to be worn by clergy as per Canon Law. It is generally edifying for the people to see their priests, deacons or even seminarians wearing the collar or cassock. In a way, clerical attire serves as the clerical equivalent of a wedding ring. Not wearing some sort of clergy clothing does not take away Orders, but generally it is somewhat suspicious for a priest to go out in āciviesā if there is no real pressing reason to do so.
