Questions
How do I know which bikini size fits my child?
Measure the child's bust and waist and compare to the brand’s size chart, as sizing can vary between labels.
Are the fabrics used in kids' bikinis chlorine resistant?
Most polyester and nylon blends are designed to resist chlorine and dry quickly.
Can I wash these bikinis in a regular washing machine?
Use a gentle cycle with cold water and avoid harsh detergents to keep colors and elasticity intact.
What features help keep a bikini in place while swimming?
Elastic waistbands, adjustable ties, and a snug fit around the hips prevent slipping.
