Various photographs of the bare legs of La Comtesse de Castiglione.
The countess enjoyed transgressing the standards of propriety for women of her social class. By addressing herself directly to male fantasies of the day, fixated on women’s legs concealed by modesty and the demands of fashion, the countess unashamedly drew inspiration from actresses and dancers from the variety theater, who wore stockings intended to tone down the shocking indecency of such a spectacle. She committed a double transgression when she had both her legs photographed naked, without protective stockings, as only low-class prostitutes and models dared. The photograph, however, shows only the lower part of the body, thereby concealing the sitter’s identity (source).
I believe I once read that the Countess thought that her legs were the most beautiful part of her body.
