A friend of mine is going to be the Chaplain to the High Sheriff of one of the Home Counties next year, a very English thing. Nothing to do with guns and that American stuff. If anyone can put something in the comments on the functions of such an exulted personnage it will be of interest.
The conversation turned to what does the Chaplain to the High Sheriff wear; important he wears something and that it is the right thing. I actually believe the old adage, "If he doesn't wear; it shows he doesn't care". My friend is known for his caring. The proper thing is a feriola, a light very full cloak with a stiffened flat collar, and perhaps a saturno, or a Roman hat, in beaver of course not felt.
For those of you who want to know more, there is a very useful book Costume of prelates of the Catholic church, according to Roman etiquette (c1909) . Best viewed on a laptop or widescreen
I am hoping that someone will do an update.
There is a very interesting bit (for some people) about the clerical collar, apparently it isn't the white sweatband but actually the coloured thing underneath, black for a priest, now purple for a bishop, red for a cardinal.
