The mermicorn print of our long-sleeved swimsuit and hat is almost as cute as the little one wearing it. Added stretch and zip fastening provide a flexible fit and make dressing easier. Quick-dry fabric is perfect for days by the pool or at the beach. Chlorine-resistant material will keep the suit looking new for longer. Endorsed by the British Skin Foundation.
