J. L. Nevinson, Origin and Early History of the Fashion Plate
“ A fashion plate is a costume portrait, that is to say, a portrait not of an individual but one which shows the sort of clothes that are being worn or that are likely to be worn. It is a generalized portrait, indicating the style of clothes that a tailor, dressmaker, or store can make or supply, or showing how different materials can be made up into clothes. A fashion plate is related to the wear of its epoch and not to the history of dress, except insofar as the dress of a historical personage may be imitated at a later date. ”
