The biretta () is a square cap with three or four peaks or horns, sometimes surmounted by a tuft. Traditionally the three-peaked biretta is worn by Christian clergy, especially Roman Catholic clergy, as well as some Lutheran and Anglican clergy. A four-peaked biretta is worn as academic dress (but not liturgically) by those holding a doctoral degree from a pontifical faculty or pontifical university or faculty. Occasionally the biretta is worn by legal professionals, for instance advocates in the Channel Islands or judges in some Polish courts.
