See Why Mermaidcore is Making a Splash and Experiencing a 614% Surge in Searches

Last summer, Lily AI covered the season’s hottest Coastal Grandmother trend. You know… the unbuttoned button-ups and preppy casual look inspired by Nancy Meyer films.

This summer’s trend could be even bigger. The Mermaidcore trend encompasses a whimsical and ethereal style inspired by the enchanting world of mermaids, and has witnessed a surge in popularity coinciding with the highly anticipated release of Disney’s live-action adaptation of The Little Mermaid.

Perhaps the celebrity who has made the biggest waves in the Mermaidcore fashion scene is none other than Halle Bailey. As the lead actress in Disney’s live-action adaptation of The Little Mermaid, Halle Bailey has been seen donning mermaid-inspired looks both on and off the red carpet.


Mermaidcore is no doubt trending right now. With a staggering 614% increase in searches on Pinterest, ‘Mermaidcore’ is having a moment. Furthermore, the fashion trend has amassed a whopping 14.8 billion views on TikTok.

With the arrival of the summer season after the movie’s release, there is a growing desire among consumers and shoppers to embrace the Mermaidcore trend. Let’s dive in.

What is the Mermaidcore Aesthetic?

This trend effortlessly blends a feminine and bohemian elegance with contemporary playfulness. Embracing inspiration from the Y2K revival, Mermaidcore introduces seashells and low-rise skirts, injecting a touch of whimsy and fun into the ensemble. Mermaidcore also pays homage to the disco era of the 70s by embracing the allure of shimmering sequins and by blending a variety of fashion elements that creates a multi-faceted aesthetic.

To curate collections that represent Mermaidcore, brands and retailers can look to include:

  • Shimmering Materials: Incorporate fabrics with a luminous and iridescent quality, such as metallic materials, holographic fabrics, and sequins.
  • Ocean-Inspired Prints: Integrate prints that evoke the underwater world and its creatures. Think fish scales, seashells, coral reefs, or even whimsical illustrations of mermaids themselves.
  • Pastel and Oceanic Color Palette: Opt for soft pastel hues reminiscent of oceanic tones, such as aqua blue, sea foam green, pearl white, and lavender.
  • Flowing Silhouettes and Draping: Focus on loose, flowing silhouettes that mimic the fluidity and grace of mermaids. Incorporate asymmetrical hemlines, cascading ruffles, and draped fabrics to add movement and a sense of ethereal beauty.
  • Embellishments: Think of textures such as ruffles, frills, lace, ruching, pearls, sheer fabrics, and of course, sea shells.
