Care instructions:

  • Rinse promptly — after swimming, rinse your swimsuit in cool water to remove chlorine, salt, and sunscreen residue.
  • Hand wash with mild soap — gently hand wash using a mild, color-safe soap. Avoid detergents, bleach, or any harsh chemicals that could damage the fabric.
  • Avoid wringing — after washing, gently press out excess water without wringing to prevent stretching or damaging the fabric.
