Chemise cagoule
A chemise cagoule was a heavy night shirt worn by Catholic men and women during the Middle Ages in order to permit a husband to impregnate his wife without having to endure any unnecessary physical contact with her. The chemise cagoule covered all sexual areas, but left an opening for necessary contact. Pious couples were expected to use chemise cagoules at every lovemaking session, and thus would never see each other naked.
