Negligee

The negligee or négligée, from the French: négligé, literally meaning "neglected", is a form of women's clothing consisting of a sheer usually long dressing gown. It is a form of nightgown intended for wear at night and in the bedroom. It was first introduced in France in the 18th-century, where it mimicked the heavy head-to-toe style of women's day dresses of the time.
