- Satin bodice with Ariel heart character motif and sequin diagonal stripe

This Kids Disney Ariel Mermaid Costume Dress brings the underwater magic of The Little Mermaid straight to your child's dress-up wardrobe. The fitted bodice features a heart-shaped character motif showing Ariel and Flounder against a glittery castle backdrop, with a diagonal sequin stripe catching the light like ocean waves.
The satin and glitter-printed fabric shimmers in turquoise and lavender purple, with vertical scale patterns running down the pencil-style tail skirt. Sheer tulle flutter sleeves sit at the shoulders for that ethereal underwater look, while the iridescent tulle fins at the hem create the signature mermaid silhouette. Elastic shoulder straps adjust easily for comfortable all-day wear.
Perfect For
Book Week & Fairy Tale Days: An instant match for any princess or fairy tale character parade, plus a natural fit for ocean and underwater storybook themes.
Disney Parties & Princess Events: The recognizable Ariel character art makes this a standout at Disney-themed birthday parties, character meet-and-greets, or any princess dress-up event.
Halloween & Dress-Up Play: The sparkle and colour hold up beautifully for trick-or-treating, school Halloween parades, or everyday imaginative play at home.
How to Wear It
Pair with red clip-in hair extensions or a long red wig to complete the Ariel look, and slip on sparkly sandals or barefoot for the full underwater vibe. A plastic fork as a dinglehopper prop (not included) gets laughs from fellow fans.
Parent FAQs
Q: What size should I order?
Check the size chart image — this costume runs true to standard girls' sizing. The elastic shoulder straps give a bit of flex, but if your child is between sizes we'd recommend sizing up for longer wear.
Q: Can she move comfortably in the pencil skirt?
Yes — the skirt has enough give for walking and sitting, though the mermaid silhouette is fitted rather than full-circle. Great for parties and photos; she might prefer regular play clothes for running around the playground.
Q: How do I wash this? Is the glitter durable?
Hand wash in cold water and air dry to protect the glitter print and sequin trim. The character motif is heat-sealed, so it holds up well with gentle care.
Q: Is this official Disney merchandise?
Yes — this is a licensed Disney costume featuring authentic Ariel character artwork and official Little Mermaid branding.
Care: Hand wash cold, air dry. Do not iron over printed graphics.
