collaret , also: collarette

Sometimes he appears with a frilled collaret and a hat, usually with a close-fitting crown and wide round brim, more rarely with a conical shape like a dunce's cap.

His overlarge cotton blouse and trousers freed him from the constraints of the woolen dress of his predecessors, and his abandoning the frilled collaret and hat gave prominence to his expressive face.

Sometimes (especially in Roman Catholic practice) 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.

He altered the costume: freeing his long neck for comic effects, he dispensed with the frilled collaret; he substituted a skullcap for a hat, thereby keeping his expressive face unshadowed; and he greatly increased the amplitude of both blouse and trousers.
