blue n.1

1. a ‘blue stocking’ [abbr. SE blue-stocking, a term that originated c.1750 when a coterie of intellectual ladies – Mrs Montague, Mrs Vesey and Mrs Ord – set out to replace London society’s trad. post-dinner pursuits – card-playing – with more cerebral amusements. Formal dress was no longer required and among those who attended their soirées was Benjamin Stillingfleet, who habitually wore grey or blue worsted, instead of black silk, stockings. Admiral Boscawen, a staunch traditionalist, labelled these events ‘the Blue Stocking Society’; the ladies were called Blue Stockingers, then Blue Stocking Ladies and finally Blue Stockings].
