Girls One-Shoulder Mermaid Sequin Swimsuit: This is the trend-right swimsuit your little fashionista will HAVE to have this season. The pretty periwinkle-blue “magic sequins” on the front reverse to silver when brushed in the opposite direction. The back is solid periwinkle that matches the trim. Best of all, it offers the confidence of UPF 50 sun protection. Pair it with our matching mermaid-tail cover-up for a complete look.
