Nightgown

A nightgown is a garment worn over the entire body during sleep. In mainstream Smurfs media, most Smurfs are seen wearing nightgowns as well as Smurf hats with fluffy tips when sleeping.

In the EMPATH: The Luckiest Smurf story series, however, some Smurfs such as Empath do not wear nightgowns when they are sleeping.
