Swim suit

A swimsuit is a general term for the type of garment worn for swimming and bathing by men and women. For men, it is usually in the form of short pants or briefs, while for women, it is either in a single piece outfit that covers the torso or in a two-piece outfit.

In mainstream Smurfs media, the male Smurfs would either wear shorts (as in the cartoon show) or briefs (as in the comic books).
