Join in the Fun

You can’t remember a time that Disney’s Ariel wasn’t a favorite costume option. And every time you can slip into a mermaid tail and purple sea-shell top, you grab the opportunity like Ariel grabs a shining dinglehopper. Though, as a parent constantly showing your kiddo beloved Disney films, you got a bit nervous you’d need to relinquish the role. Luckily, while your little ones have a curiosity and penchant for discovering random treasures like Ariel, they’re more concerned with being involved in your antics than changing your trends. So, the next time you transform into Ariel, your sweet sidekick can be ready for the adventure, too!

Design & Details

It’s time for our exclusive Disney Flounder Toddler Costume from Disney’s The Little Mermaid! This officially licensed ensemble makes becoming Ariel’s constant companion quick with two easy-to-wear pieces. Bright yellow and blue velour fabric creates a super-soft bodysuit and hood that fasten with a zipper on the suit and hook-and-loop fastener strip on the hood. Two-toned blue sleeves fan out from the bodysuit and give your toddler functioning fish fins. A matching tail is attached to the back of the suit as well, so your little one will be ready to swim beside you on any adventure! Meanwhile, the soft hood features a blue fin designed after Flounder’s “hair.” Fiberfill is used to sculpt his very squishable cheeks and nose. And Flounder’s bright eyes come to life through embroidery.

Q: I see the size only goes up to 4t, is their a little bit of stretch to the costume (1 Answer)
Asked by Rebecca | August 22, 2022

Costume sizes are very different than regular clothing sizes, and do vary from costume to costume. The best way to order is by taking your measurements, add 3-4 inches to them for movement, and compare them to those listed on the product page. These are the EXACT measurements of the costume that we take right here in our warehouse. If you find that you are between sizes, we always recommend going with the size up!

    Great costume!

    Loved this costume. It fit well although the hat did keep falling down close to his eyes. It’s great for cooler weather. It kept my 4 year old warm with enough room for a sweatshirt underneath. Really well made and we received many compliments.
    Bottom Line Yes, I would recommend this to a friend.

    Perfect costume for a Little Mermaid lover! I ordered a size up for my toddler & it is big on her, but I like it better that way!

    Cute. The hat does run big. I'll have to put stuffing in it so it stays out of my child's eyes but other than that it fits.
