Corsets were made of a variety of materials, depending on the time period and the fineness of the article. The main fabric for the body of the corset might have been linen, stiffened with paste or starch. Lower-class women would have worn corsets of a cheap, sturdy cotton cloth. Corsets were also made of decorative fabrics like satin or silk. The whalebone used to stiffen corsets was technically not bone at all but the teeth-like structures, called baleen, of a baleen whale. Baleen whales have hundreds of horny plates arranged in their upper jaws that serve to sieve tiny marine animals out of the water. Baleen is somewhat of an intermediary material between horn and hair, made up of many parallel hair fibers encased in hard enamel. Each baleen plate is about 10 in (25.4 cm) wide and 9-13 ft (2.74-3.96 m) long. Baleen can split along the parallel fibers and—when softened by steam—is easily shaped. Once dry, it holds its shape proving to be an enormously useful material for corset-making. Over-fishing led to the demise of baleen whale populations, and corset makers were driven to find substitute materials. They used cane or steel, and later plastic. The corset maker inserted thin slivers of whalebone into the corset to hold its shape. Whalebone was also used in some corsets for a front piece called the busk. The busk gave a smooth line to the front of the corset and was also sometimes made of wood, horn, or steel. GOOGLED THAT lol, quite interesting though
