1756, "a kind of loose gown worn by women," from Fr. négligée, from fem. pp. of négliger "to neglect," from L. neglegere (see neglect). So called in comparison to the elaborate costume of a fully dressed woman of the period. Borrowed again, 1835; the modern sense "semi-transparent, flimsy, lacy dressing gown" is yet another revival, first recorded 1930.
