Who Doesn't Love a Mermaid?

Like so many TikTok trends, #mermaidcore began as a fashion statement featuring lots of pearls, opalescent textures, girly ruffles, sheer fabrics and seafaring color schemes of blue and green. Rather than the organic, linen and white-centric vibe of coastal grandma, #mermaidcore is more cool-girl ethereal defined by slinky, sheer, sexy, shiny acquamarine details. Think Sara Paxton as Aquamarine, Daryl Hannah in Splash, the sugary green and blue The Little Mermaid palette and you have a sense of the ultra-feminine, pretty, beachy mermaidcore look. Learn more: We've gathered a host of ideas for bringing mermaidcore into your home decor.

A Stunning Seashell Installation

Eighties-era mauves, lavenders and roses are enjoying a resurgence, especially when married with a contemporary spin. Here, a striking installation of seashells also gives this bedroom an on-trend mermaidcore look.

Ethereal Meets Seaside Decor

Sea-inspired decor and beach finds don't have to be ultra-casual or nautical. Here seashells and coral are dressed up to fit right into a dreamy sea life vignette.

Create an Under-the-Sea Party

A white ruffle shower curtain is used as a backdrop for this dessert table, adding a perfect effect: like white ruffled waves. A repurposed chandelier from a bedroom hangs over the dessert table lending more shimmer to this under-the-sea celebration.

Bringing the Ocean's Outside Inside

Bringing a very mermaidcore, nautical aesthetic to this room is a DIY seashell mirror, a lovely way to display beachcombed treasures.

A Capiz Shell Pendant Brings the Shimmer

Capiz shells, popularly used for many different decorative purposes, come from windowpane oysters, which are found on muddy shores near bays, coves and lagoons. The shells are harvested and transformed by artisans into one-of-a-kind organic works of art. To create this oversized pendant light, hundreds of capiz shells were gathered, shaped, cut to size, then inlaid to a steel frame. Once illuminated, the shells cast a filtered pearlescent glow throughout the space.

This Modern Light Fixture Is Like a Cascade of Bubbles

Combining both a bubble motif and a shimmering, reflective surface, this glass chandelier is the perfect choice for a subtle mermaidcore design flourish.

Create a Special Beachy Vibe at an Al Fresco Dinner

Soft blues and greens and a beautifully romantic, draped tablecloth are all you need to add a little mermaidcore magic to an outdoor tablescape.

Succulent Planting in Conch Shell

Not just rendolent of the sea, planting succulents in large seashells like this conch is a pretty, easy way to bring a lively, beachy vibe to your space.

A Fun Bubble Vignette

Give any room an instant under-the-sea attitude with stenciled bubbles.

A Mermaidcore Costume

It's never too early to start sourcing your next costume party look. Add a glamorous, sleek dress in a coastal shade of blue or green, and you've created the perfect mermaidcore moment.
