PRODUCT DETAILS
What's in the Box
- Mermaid princess dress with attached sleeves and floor-length fin train
This Kids Mermaid Princess Costume brings the magic of underwater royalty to Book Week and fairy tale dress-up days with an aqua blue bodice, lime green mermaid tail skirt, and a show-stopping seafoam fin train that trails behind. It's the dress-up moment every ocean-loving kid dreams of.
The bodice shimmers with iridescent turquoise panels edged in silver glitter trim, while sheer puffed sleeves create the off-shoulder princess look. The mermaid skirt tapers at the ankles then flares into a dramatic transparent fin — the kind of detail that makes playground arrivals memorable. Glitter-dusted throughout, durable enough for a full day of swimming pretend.
Perfect For
Book Week & Fairy Tale Days: A natural fit for mermaid stories, underwater adventures, or any princess-themed Book Week parade at school.
Dress-Up Parties & Halloween: The go-to for princess parties, ocean-themed birthdays, or Halloween trick-or-treating with a magical underwater twist.
Imaginative Play: Perfect for kids who spend afternoons arranging underwater kingdoms in the backyard or narrating mermaid adventures to their toys.
How to Wear It
Pair with a sparkly tiara and comfortable flats (the fin train makes heels unnecessary). Let your child's hair flow loose or braid it with sea-themed hair clips for full mermaid effect.
Parent FAQs
Q: What size should I order?
A: Check the size chart for chest and length measurements. The bodice is structured, so if your child is between sizes and has a fuller chest, size up for comfort.
Q: Can they walk easily in the mermaid tail?
A: Yes — the skirt tapers but doesn't restrict steps. The fin train drags along the floor, so watch for tripping on stairs. Best for indoor school events or supervised outdoor use.
Q: How do I wash this without damaging the glitter and sheer fabric?
A: Hand wash in cold water or use a delicate machine cycle inside a mesh bag. Air dry flat — the sheer sleeves and fin train are delicate, so avoid wringing or tumble drying.
Q: Is this suitable for a full school day?
A: Absolutely. The bodice has shoulder straps under the sheer overlay for support, and the skirt allows normal walking. Just remind your child to gather the train when climbing or sitting.
Care: Hand wash cold, air dry flat. Avoid heat to preserve glitter finish.
