A short encyclopedia entry defining crinoline, originally a fabric with a flax warp and horse-hair weft, and later the stiff petticoat or hoop skirt used to expand women's dresses. It covers the word's French and Latin origins, the materials used for hoops (cane, whalebone, steel wire), and the fashion's history from Elizabethan farthingales through the 1850s hoop. An engraving shows Elizabethan costume of 1575 with a farthingale skirt.
