If our original Mermaid Bikini wasn’t enough for you, we’re back with a more streamlined, svelte, supercharged version made for full-throttle, high-performance mermaiding.

Take this for a dip in the Mediterranean and your best childhood imaginations will come flooding back to you. You’ll start to feel magical powers, begin to befriend parrotfish and see the love in the eyes of nearby crabs. You’ll gain the sense that you’ve already obtained all the treasures of the ocean and that all is right in the world.

Are you a sustainable brand?

We drop in small, limited quantities to avoid waste. Read more here.

What even is this brand?

If you're new here, welcome bestie! We're a 1.5 year old startup based in Brooklyn, NY. We're a small team and so happy you're here to join us on our journey to girl domination. Read more here.

Where do you ship from?

We actually have a few warehouses - two are in the US, while one is near our factories in Asia. This helps us get our products launched and in your hands more quickly, and uses fewer resources.

Are you a dropshipper?

No! All of our products are developed in-house and produced specifically for our brand, with months of research, sampling, and quality checking along the way.

Who designs your shoes?

While I (Sarah) am in charge of all things creative, I like to think you are part of the design team, too. We get your input on design concepts regularly throughout the development process on social, newsletter, and here on our site. Like shopping with your bestie, but different.

Are your shoes true to size?

We try to be, but some styles run small. You'll see a size note on this page if they do.
