How to take care of girls’ swimsuits
Proper care and maintenance of your girls’ swimwear pieces will preserve their sun-protective properties and extend their lifespan. Follow these steps to keep her favorite piece in excellent condition throughout the hot summer:
- Rinse the swimsuit in cold water immediately after each use. This removes salt, chlorine, and other chemicals that can damage the fabric over time.
- Hand wash using mild detergent. Avoid bleach or fabric softeners, which break down the fibers and reduce the UPF protection. For competition swimsuits especially, gentle washing preserves the shape and elasticity.
- Line dry in the shade or tumble dry on low heat. High temperatures from direct sunlight or hot dryers can degrade the UPF 50-rated fabric and vibrant designs. Our quick-drying, stretchy fabric typically air dries within a few hours.
- Store in a cool, dry place away from direct sunlight when not in use. This maintains the bold color and patterns while preventing unnecessary UV exposure to the fabric.

Dressing for beach fun and pool time goes beyond selecting a basic suit. With thoughtful styling and the right accessories, your little one can create stylish sun-safe looks for any water adventure.
