Tudor bonnet

The cap is worn as traditional clothing with gowns and represents suitable headgear especially for livery and burgess guild officers.

Tudor bonnets can be made of velvet or cloth, usually black but sometimes in other colors.

Gold is common in academic caps, but in Oxford and some other institutions a black ribbon is traditional.

In many North American educational institutions it is usual for holders of doctorates to wear a soft, brimless, tam or traditional mortarboard instead.

The biretta also sometimes appears among holders of theology degrees or officers at religious institutions.
