Negligee

A negligee or (more correctly) negligée is a lightweight dressing gown or similar item of bedroom wear, often see-through, mostly worn by women. The word is French, literally meaning "neglected". In France, it is known as a "déshabillé".

Wearing a see-through negligee with nothing, or only lingerie underneath but refusing to allow things to go further could be a tease and denial.
