Fur was worn, mostly as a lining layer, by those who could afford it. The grey and white squirrel furs of the Middle Ages, vair and miniver, went out of style except at court, first for men and then for women; the new fashionable furs were dark brown sable and marten. Toward the end of the century, wild animal furs such as lynx became popular. Ermine remained the prerogative and hallmark of royalty.
