A robe is a loose-fitting outer garment. Unlike garments described as capes or cloaks, robes usually have sleeves. The English word robe derives from Middle Englishrobe ("garment"), borrowed from Old Frenchrobe ("booty, spoils"), itself taken from the Frankish word *rouba ("spoils, things stolen, clothes"), and is related to the word rob. There are various types of robes, including:
A "bathrobe" worn mostly after bathing or swimming. A typical bathrobe is made of an absorbent material such as towelling, and might be worn at home after a bath, to keep warm and preserve modesty if there is no need to dress. A similar garment not made of absorbent material might be called a dressing gown or housecoat. See, for example, that worn by the fictional character Arthur Dent.
(Informal usage) Any long flowing garment; for example, a cassock is sometimes called a robe, although a cassock is close-fitting.
