Swimwear that can be worn as shorts

BOARDIES

Think of what surfers often wear that’s both quick-drying and stylish at the beach.

This clue points to "BOARDIES," a type of men’s swimwear that doubles as casual shorts. The name comes from "board shorts," often worn for surfing or beach activities, with the playful "-ies" suffix making it sound like a nickname. It fits because boardies are designed to be worn both in and out of the water, just like shorts. The clue keeps it simple by describing their dual purpose.
