Reviews Summary
Customers say this mermaid costume is adorable and well-made, with beautiful colors and accessories including a shell crown and wand. Many note the costume runs small and recommend sizing up 1-2 sizes for comfortable fit. The material can be itchy for some children, causing red marks. Several mention the crown is heavy and fragile, with shells occasionally falling off, though hot glue fixes this easily. The wand tends to break easily during play. Many appreciate the costume's quality compared to typical Halloween costumes, with some finding the material softer than expected. A few note the crown has an unpleasant odor from real shells.

    Cute costume

    Outfit was a hit. She looked adorable. However, it is itchy material and we had to go up at least 2 sizes for it to fit her comfortably. I did order early and was able to get on time

    Adorable costume! Purchased this for

    Adorable costume! Purchased this for my six-year-old granddaughter's birthday. She loves it! My granddaughter is slim and tall. This costume runs small on her. Would purchase again.

    Mermaid

    Very cute. My daughter is obsessed. I love the crown, but it is fragile. Hot glue works wonders if the shells fall off. I'd order a size up because the costume runs small, in my opinion.
