DISH-A-BILLE', or DISH-A-BIL', n. [disabil'; Fr. deshabillé; des and habiller, to dress. See Habit.]

An undress; a loose negligent dress for the morning. But see Deshabille, the French and more correct orthography. Dryden uses the word as a participle, “Queens are not to be too negligently dressed or dishabille.” In this use he is not followed.
