The woman in this plate is wearing a very large cashmere shawl. Her dress has a very wide skirt, probably supported by a crinoline. A crinoline was a stiff underskirt that supported the wide skirts of the era. Abstract source: Boucher, François. 20,000 Years of Fashion. New York: Harry N. Abrams, Inc, 1967.
