Underpants

Underpants are a garment that is worn around the waist, usually under a pair of pants or a skirt.

In the EMPATH: The Luckiest Smurf story series, underpants are worn by every Smurf in the village, both male and female. Most underpants are usually in the form of a pair of white briefs, though Showoff specializes in various types of boxer-style underwear, which can at times be embarrassing to show when a Smurf accidentally drops his pants.
