Mermaid Costumes for Women

Our mermaid costumes lean on pearl, sequin, and iridescent finishes in sea greens, blues, and shell tones, not a stiff fishtail suit. Handmade in Stockholm for Halloween, festivals, and pool parties, each piece is built to wear again, so the look works long after October 31.

Mermaid Costumes to Shop First

How We Make the Mermaid Look

Every piece here is handmade to order in our Stockholm studio, with pearls and sequins set by hand so the sea colors catch light from every angle and the fit moves with you. The look comes from palette and finish, iridescent greens, blues, and shell tones, rather than a rigid tail, which is why it carries a Halloween party, a festival, and a pool party alike. For more of the same shimmer, our sequin dresses and festival bodysuits share the finish. If you want costume ideas, our sexy Halloween costume ideas guide covers the mermaid angle too.

Questions About Mermaid Costumes

What makes a good mermaid costume?

A mermaid costume works best on finish and color, not a rigid tail. Sequins, pearls, and iridescent fabrics in sea greens, blues, and shell tones read as under-the-sea, especially on a fitted bodysuit, jumpsuit, or two piece. A shell or pearl accessory finishes the look.

Do the mermaid costumes have a tail?

Our take skips the stiff fishtail so you can actually dance. The mermaid look comes from the palette and finish, pearls, sequins, and iridescent shimmer, on pieces you can move and travel in. Add a shell or pearl accessory if you want to lean further into the theme.

Are these mermaid costumes only for Halloween?

No. The sequin and pearl pieces carry a pool party, a festival, or a themed night just as well as Halloween. Each one is festival-grade and made to wear again, so you are buying a reusable look, not a single-night costume.

How fast can I get a mermaid costume before Halloween?

We ship worldwide with DHL Express, usually within a few days, and pieces are made to order. Order a couple of weeks ahead to be safe, and sooner through October when demand climbs. Contact the team if you need a firm arrival date and we will confirm what is possible.
