Key Buying Factors
01
Fit
Ensure a snug yet comfortable fit around the legs and waist to prevent gapping and provide security during play. Adjustable features like drawstrings or snaps are a plus for growing babies.
02
Fabric
Look for lightweight, quick-drying materials with high UPF ratings. Chlorine and saltwater resistant fabrics maintain their shape and color over time, offering lasting wear.
03
Quality
Durable stitching and robust hardware, like zippers or snaps, are indicative of high-quality swimwear. Garments should withstand frequent washing and sun exposure without fading or stretching.
04
Style
Beyond adorable prints and vibrant hues, consider design elements that enhance practicality, such as full-coverage rashguards for extra sun protection or easy-on, easy-off closures.
Section 05
Care, Cost and Maintenance
After Each Wear
Rinse thoroughly with cool, clean water immediately after use to remove chlorine, salt, and sand. This helps preserve fabric integrity.
Washing
Hand wash gently with a mild, pH-neutral soap. Avoid harsh detergents or bleach, which can degrade fabric and fade colors. Lay flat to dry away from direct sunlight.
Storage
Ensure swimwear is completely dry before storing in a cool, dark place. Avoid prolonged exposure to high heat or humidity, which can encourage mildew.
Pro tip
Layer a wide-brimmed hat and protective sunglasses with any swimwear ensemble to complete the look and offer additional sun safety for your little one.
