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.
