Roll everything and use a wet bag.

Roll your beachwear instead of folding it — that’s the trick for minimal wrinkles. Beachwear is usually stretchy and forgiving, so even if you get a few creases, they’ll fall out once you put things on.

Fold-and-stack is what crushes your cover-ups. Rolling distributes pressure evenly and keeps your swimsuits from getting those weird fold lines. For damp suits, pack a dedicated wet bag (or a plastic grocery bag) so nothing else gets soggy. Flip-flops go on top or in outer pockets; they don’t need much care.

You’re really overthinking this. Beachwear is built to survive salt, sand, and chlorine. A trip in a suitcase won’t hurt it.
