She'll have lots if fun all day in this 2 Pc. Mermaid tankini swimsuit by Ruffle Butts. All Ruffle Butts swimwear have UPF 50+ in the fabric to block harmful rays of the sun. And, while all that protection is wonderful, we just love this scalloped pattern in aqua, pink and purple as well as the flutter sleeves and ruffles in the back. And, for little sister, the "Mermaid" One Piece Rash Guard is a perfect combination for a great day at the pool or beach. You can view the entire "Ruffle Butts Summer Collection" here.
