1pc Yellow Mermaid Costume
Guarantee Safe Checkout
Who wouldn’t want to be a mermaid? With our 1PC Yellow Mermaid Costume, you can become your favorite fantasy creature in a matter of moments. This strapless romper is a stunning, eye-catching yellow with scale print. The nylon/spandex blend clings to your curves and has a subtle shimmer when the light shines on you, giving you a little extra sparkle anywhere you go. The bust of the romper is topped with a curve of white material to draw attention to your chest and create the illusion of a mermaid’s seashell bra.
Whether attending a Halloween party or a rave, you’ll be giving off all the mermaid vibes. The leg cutouts of the romper with yellow ruffled material mimic the look of a mermaid’s fins without constricting or covering those gorgeous legs. If you want to add more detail to your mermaid ensemble, we recommend pairing this romper with our Fingerless Elbow Length Mermaid Gloves and a Shell Necklace.
Our 1PC Yellow Mermaid Costume is available in small, medium, and large sizes.
