A chastity belt is a locking item of clothing that prevents the wearer from engaging in sexual intercourse and (sometimes) masturbation as well. Versions exist for both male and female. One of the first chastity belts photographed was perhaps from Ostra Studio, the same belt is also seen photographed by Yva Richard.
Jacques & Charles Biederer photographed females in chains & chastity, but more photographers had a special interest in females in chains.
Like Rudolf Franz Lehnert who photographed real slavegirls in oriental harems.
