PRODUCT DETAILS
What's in the Box
- Scale-print dress with fitted bodice and multi-layer tulle skirt
- Attached mermaid tail fin (floor-length train)
- Shell-shaped waist embellishment
- Tulle bow shoulder strap accents
This Kids Mermaid Costume turns Book Week morning into an under-the-sea moment — iridescent scale-print bodice, rainbow-pastel tulle skirt, and a floor-length mermaid tail that fans out behind like she's just surfaced from the reef. The tail is sewn to the back waist as a dramatic train, so she can still walk and play while the fin trails along.
Bodice shimmers with holographic lavender-and-aqua scales that catch the light, paired with a white shell appliqué at the waist and tulle bows on the shoulder straps. The skirt is layered tulle in mint, pink, white, and purple — soft, floaty, and very twirl-worthy. Stretchy comfortable wear through the bodice; the tail drapes behind without tangling around legs.
Perfect For
Book Week & Fairytale Parades: A natural pick for any fairytale or ocean-themed storybook character, Hans Christian Andersen-inspired fantasy days, or underwater creature dress-up events.
Princess & Ocean-Themed Parties: Birthday parties with sea creature themes, aquarium excursions, or any event where mermaids and underwater magic rule the day.
Halloween & Dress-Up Play: Halloween trick-or-treating, kindy photo day, or weekend dress-up at home — the tail makes an entrance without tripping her up.
How to Wear It
Pair with neutral sandals or barefoot for beach-y vibes. Hair in loose waves or a high bun with a shell clip completes the underwater-princess look. Skip heavy accessories — the shell waist detail and tail are the stars.
Parent FAQs
Q: What size should I order?
Check the size chart for chest and length measurements. The bodice has some stretch through the scale-print overlay, but if your child is between sizes, size up for a longer wear window.
Q: Will the tail get in the way when she walks?
The tail is a back-draping train, not a leg-wrap — she can walk and run normally. It trails behind like a bridal veil, adding drama without restricting movement.
Q: Can she wear this indoors for a school parade?
Absolutely. The tail is lightweight tulle and won't snag on classroom chairs. Just remind her to gather it when sitting down, same as a princess gown.
Q: How do I wash this without damaging the tail or tulle?
Spot clean the bodice and tail, or gentle hand wash and hang to dry. The iridescent scale print and shell appliqué do best with air-drying — skip the dryer to keep the shine.
Care: Spot clean or gentle hand wash; hang to dry. No tumble dryer.
