Brunette Girl Strips Her Undergarments

Over the upper part of their bodies, both medieval men and women usually wore a close-fitting shirt-like garment called a chemise in France, or a smock or shift in England. The forerunner of the modern-day shirt, the chemise was tucked into a man's braies, under his outer clothing. Women wore a chemise underneath their gowns or robes, sometimes with petticoats over the chemise. Elaborately quilted petticoats might be displayed by a cut-away dress, in which case they served a skirt rather than an undergarment. During the 16th century, the farthingale was popular. This was a petticoat stiffened with reed or willow rods so that it stood out from a woman's body like a cone extending from the waist.
Corsets also began to be worn about this time. At first they were called pairs of bodies, which refers to a stiffened decorative bodice worn on top of another bodice stiffened with buckram, reeds, canes, whalebone or other materials. These were not the small-waisted, curved corsets familiar from the Victorian era, but straight-lined corsets that flattened the bust.
There is a myth that Crusaders, worried about the fidelity of their wives, forced them to wear chastity belts. There is no reference, image, or surviving belt to support this story. Most historians of this period are of the view that a chastity belt was worn to prevent sexual assault and that the woman kept the key.
Men's braies and hose were eventually replaced by simple cotton, silk or linen drawers, which were usually knee-length trousers with a button flap in the front.
