Bathrobe

A bathrobe is a garment worn over the torso when somebody is preparing to take a bath or shower or is about to go into a sauna.

In the EMPATH: The Luckiest Smurf story series, the Smurfs wear bathrobes whenever they prepare to take baths. Empath wears a bathrobe inside his home whenever he prepares to go to sleep at night, as sometimes does Smurfette.
