What did the Carthusians wear?

They were/are known as White Monks, because of their white cowls (usually only worn as choir dress). Their regular habit consists of a white tunic, over which a black hooded scapular is worn. The whole is girded together by a leather belt. (Some Cistercians of the Common Observance [OCist] wear, instead of the leather belt, a black cincture, BUT Cistercians of the Strict Observance [OCSO] never do, they only wear leather belts).
