Setup: Before first use, adjust the convertible back straps to your preferred style (straight or crossed) and tightness for a secure yet comfortable fit. Ensure the underband sits firmly but not tightly under your bust, providing proper support. Compatibility: This swimsuit is specifically designed for adult females seeking active swimwear. Care: To maintain the integrity and longevity of your swimsuit, hand wash only in cool water with a mild detergent. Do not bleach, tumble dry, iron, or dry clean. Rinse thoroughly after each use, especially after exposure to chlorine or salt water, and gently squeeze out excess water. Lay flat or hang to dry in the shade, away from direct sunlight, to prevent fabric degradation and fading.
