This robe without sleeves is worn over an alb or rochet as part of the vestments of a bishop. At first it was simply the outer garment in general use. It was of one piece with openings for head and arms. Not until the introduction of wigs did it open down center front. The chimere was usually of black or red silk when it was adopted for liturgical or ceremonial use. As an outer garment, the chimere is not usually appropriate when a chasuble or cope is worn.
