Английский Этимологический словарь - bluestocking

- 1840, put-down for a woman considered too learned, traces to a London literary salon founded c.1750 by Elizabeth Montagu on the Parisian model, featuring intellectual discussion instead of card games, and in place of ostentatious evening attire, simple dress, including Benjamin Stillingfleet's blue-gray tradesman's hose in place of gentleman's black silk, hence the term. None of the ladies wore blue stockings.
