Rachel restock!! 🐚✨ And she brought us SO many new pieces this time!

If you’ve been in the shop, you know Rachel’s jewelry is one of my absolute favorites. She’s a local Key West artist and somehow every time she comes in she brings something I haven’t seen before. 😍

So many shells, genuine gemstones, pearls, sea glass, jellyfish, funky statement pieces, bracelets, rings… and some seriously cool necklaces. Everything feels like a little piece of the ocean. 🌊

A lot of her pieces are one of a kind, so if you see one you love, don’t wait on it. 😂

Come see all the new goodies! 🧜‍♀️💜

P.S. Can we talk about those cowrie shell rings?! 🐚😍

Okayyy these new arrivals 😍

So many fun tropical prints, easy little dresses and the cutest sets — all lightweight, breezy and basically made for Key West. ☀️🌺

And can we PLEASE talk about that “PEACE • MAGIC” resort set?! 🔮🌴 The wide-leg pants, the little matching top, the moons and palms… it might be my favorite. It feels very Mermaids Cauldron goes on vacation. 🤣👏

🚨 MERMAID SIGHTING ON DUVAL STREET 🚨 🧜‍♀️🌴

Just another totally normal day in Key West… when a real-life mermaid was spotted hanging out on Duval Street. ✨

Witnesses say she was spotted right outside The Mermaids Cauldron, which honestly feels a little suspicious. 👀😂

Coincidence? We think not. 🧜‍♀️🌊💜

You truly never know what you’re going to see walking down Duval Street!

Okayyyy Honey Swim 😍👙🌴

Our newest Honey Swim arrivals are here and while the colors and prints obviously got us first… THE FABRIC. You seriously need to feel these in person.

Their signature ribbed swim fabric is buttery soft, stretchy, supportive and double-lined with the same high-quality fabric throughout. It has that amazing substantial feel without feeling heavy — basically the kind of swimsuit you put on and immediately understand why it feels different. 🙌🏼

And can we talk about these COLORS?! 🩵🩷💜

We brought in a mix of bikinis + one-pieces, different top styles and some seriously fun Key West-worthy prints. 🌊☀️

Come in, FEEL THESE 😂, try one on and find your new favorite suit.

✨ ARTIST HIGHLIGHT: RACHEL ✨

Our favorite local jewelry maker has been busyyyy. 😍🐚 These are just some of the beautiful pieces currently in the shop!

Rachel mixes elements of the sea with genuine gemstones like Ocean Jasper, turquoise & more to create jewelry that feels like a little piece of Key West you can actually take home. 🌊💎

Think gorgeous statement necklaces, one-of-a-kind earrings, shells, stones, ocean-inspired details… and now we’ve added her CONCH SHELL ANKLETS and we are obsessed. 🐚✨
