Property of a wet suit or shapewear

TIGHTFIT

Think of how these garments hug the body to serve their purpose effectively.

A wet suit and shapewear share a key trait—they’re designed to cling closely to the body, which is exactly what "tight fit" describes. The clue plays on the literal function of both items, where snugness is essential for warmth (in a wet suit) or shaping (in shapewear). No wordplay here, just a straightforward definition pointing to how these garments are meant to feel when worn.
