A Constant Companion

Do you ever wish you could bring your baby wherever you went? Obviously, the two of you are virtually connected at the hip, but it can feel a touch awkward if you’re showing up in a fully decked-out costume and your little one is just sporting a regular jumper. We know that Disney’s Ariel loves to collect all sorts of unique things from the surface, but we’re pretty sure an infant from the surface would be crossing a line! So, whether you’re swimming around in Atlantica or running around on the surface above, Flounder is the perfect way to keep your child costumed up in a similar style!

Design & Details

Bring everyone’s favorite fishy friend to the party when you dress up your adorable kiddo in this officially licensed Baby Disney Flounder costume from Disney’s The Little Mermaid. This quick costume is a Made By Us design that comes in two parts. The first is a bright yellow and blue jumpsuit made of soft velour fabric. It zips up the back and features fin-shaped sleeves and an attached rear fin as part of the bubble suit bottom to ensure your kid is as cute as can be. The soft hood fastens with hook and loops and features detailed embroidery and fiberfill stuffing to create a squishy Flounder face!
