More about dishabille
Dishabille or deshabille “the state of being dressed in a careless, disheveled, or disorderly style or manner,” comes from French déshabillé, the noun use of the past participle of the verb déshabiller “to undress.” The French prefix dés– is a regular development of the Latin prefix dis-, which often has, as here, a reversing force (like un– in the English pair tie and untie). The French verb habiller “to dress,” originally “to trim and smooth (a log for working), to arrange, prepare,” comes from Vulgar Latin adbilāre, abbilāre, a derivative of bilia “log, tree trunk” (originally a Gaulish word). The h– in habiller comes from the French noun habit “clothing” (from Latin habitus “physical condition, appearance, dress”). Dishabille entered English in the 17th century.
