Here, we tentatively offer the unlikely yet wonderful Augustinian Cardinal/Archbishop's Priest's Biretta. The statistical chance of seeing something like this, ever, is slim, and we're keeping the whereabouts of these secret; it would ruin the surprise of sighting one. But what could be more elegant than a watered silk biretta lined in ruby silk? Ah yes, this. A watered silk biretta lined in ruby silk which blots out the sun. Naturally.
