Care, Cost and Maintenance
Washing
Rinse with cold water after each use to remove salt, chlorine, and sand. Hand wash with mild detergent, avoiding harsh chemicals.
Drying
Lay flat to dry in shade, away from direct sunlight, which can fade colors and damage elastic fibers.
Storage
Store in a cool, dry place. Avoid folding over straps or elastic to maintain shape; hang or lay flat.

For a seamless date-night look, pair a ruffled one-piece with a wide-brimmed sun hat and soft linen shorts for effortless after-swim style.
