After the French Revolution (1789–99), people began to reject obvious signs of wealth. The large buckles and elaborate patterned silk shoes of earlier days were replaced with simple, plain flat-soled slippers. Slippers were made of thin kid, the skin of a baby goat, or cloth. The toes of slippers were either pointed or rounded, and the throat of the shoe, or the opening at the top of the foot, was cut into a U or V shape. The throat was left plain or a small bow was added. Slippers were often dyed to match a woman's pelisse (a light-weight coat), sash, or gloves. Light colors of green, pink, and purple were popular. Slippers first became popular for women, but by the nineteenth century men wore black slippers to formal events as well.
