Adult Mermaid Costumes


You never outgrow your love of mermaids, and you shouldn’t have to! You may be a grown woman, but there’s still a part of you that dreams of splashing your way through the water as this mythical creature of the sea. That’s totally natural, because mermaids are elegant and beautiful, just like you. Look ready for an enchanted ballroom or an underwater adventure in a purple corset with pearl decorations along with a scaled shimmering mermaid skirt.

Kids Mermaid Costumes


Kids will love getting to glam themselves up as Ariel, complete with wig, or Mermicorno from tokidoki in our officially licensed mermaid costumes. Dress to impress with a toddler seaquestrian mermaid costume featuring a 3D seahorse that’s impossible not to notice. From a baby mermaid costume for the littlest sea/land creature on up through the ages, she’ll love how her scales reflect in the sun. Complete her mermaid look with mermaid face decals, a shell tiara, and a reversible sequin tote bag.
