If the Little Mermaid is one of the stories you treasure most, this collection of adult Little Mermaid costumes is exactly where you need to be!
Pick your favorite character and dive into the collection to find the style that's sure to make a splash in group costumes, costume competitions you intend to win, and so much more.
Start with Ariel. This Disney Princess has three distinct outfits to choose from and our collection offers her signature tail and bandeaux in a few styles. If you want to stick to her mermaid style, pick between mermaid dresses for the mermaid.
Each dress features a fit-and-flare skirt for to give wearers a stylish mermaid tail. Whether it sparkles, drapes matte and demure to the floor, or separates into pants is up to you! Choose more revealing options with flirty tops and full-coverage styles appropriate for any event.
For Ariel on land, choose between her blue dress for an adventure through new or familiar neighborhoods. Or get dressed for a royal time alongside Prince Eric with the ballroom-ready pink gown we all wanted to take a turn in as kids!
Speaking of Prince Eric, we keep it simple for fans looking to dress as the all-around charmer. Get dressed in the white top, blue pants, red waistband, and boots with either a vendor exclusive or our Made By Us version. Both offer all the essentials in standard and plus sizes. All you need to decide is which fabric finish you want for the garments included.
If King Triton is more your speed, our Disney-licensed style gives fans the regal shimmer the aquatic king deserves. Meanwhile, our Made By Us Poseidon costume or a sassy merman costume give the King storybook and fantasy flair. Just don't forget a trident!
Along the same powerful style is of course the sea witch queen herself Ursula. Choose Ursula costumes with inflatable tentacles to really show up with all the impact when you pick available exclusives and Disney-licensed Made By Us styles. Give Ursula a sassy update with costume dresses that fall above the knee while keeping all the distinctive features the character needs. Or transform into Ursula's alter ego Vanessa with our exclusive offering!
Fill out a full group costume or dream up unique couples styles by adding a costume for Ariel's sidekicks or Ursula's poopsies. With playful styles for Flounder, Sebastian, Flotsam, and Jetsam, you've got everything needed for the most inclusive retelling of Little Mermaid.
