While the competition for the ultimate song of the summer is always intense, Zara Larsson is already making a definitive case for the title. The Swedish pop star has been captivating audiences while promoting “Midnight Sun,” most notably during her appearance at Billboard’s Women in Music event. While her vocal performance was exceptional, her wardrobe—an aquatic-themed masterpiece adorned with shimmering starfish and seahorses—stole the spotlight. Styled by Caterina Ospina and designed by Rohit Mane, the ensemble was a sparkling celebration of warm-weather energy. This high-profile moment reinforces a movement that has been gaining momentum since Chanel’s Resort 2027 presentation in Biarritz: Summer 2026 is officially the season of the mermaid.
Designer Rohit Mane envisioned the look as a literal interpretation of ocean life, aiming to create a crystallized, reflective aesthetic that appeared as if Larsson were a “dripping mermaid” emerging from the waves with sea life clinging to her. This sense of escapism and sensuality was precisely what Ospina sought to define Larsson’s current artistic era. Having tracked Mane’s work for months, Ospina noted that his ability to manipulate textures and materials into fluid, contemporary silhouettes made him the ideal collaborator for a look that is fresh, confident, and quintessentially summer.
This whimsical energy was mirrored on the high-fashion runways of Biarritz, France, where Chanel’s Resort 2027 show took place just a day prior to Larsson’s performance. Creative director Matthieu Blazy balanced the house’s storied heritage with a futuristic “sea siren” aesthetic, closing the show with a series of sequin-heavy, iridescent gowns. These designs felt like a luxury wardrobe for a modern-day Ariel—a sentiment echoed by global icons like Jennie of Blackpink, who has previously leaned into this ethereal red-carpet style. The appeal of mermaidcore lies in its blend of fantasy and self-assurance, offering a playful yet mysterious way to stand out during the sun-drenched months.
For those looking to bring this runway trend into their daily rotation without a custom couture budget, Ospina suggests focusing on subtle, wearable details. Transitioning into mermaidcore is about embracing iridescence, sheer layering, and a specific color palette of seafoam greens, ocean blues, and luminous pearl whites. Incorporating organic elements like shell jewelry can instantly elevate a look without feeling costume-like. The goal is to achieve an easy, fluid silhouette that feels effortless and fresh—the perfect style philosophy for the upcoming season.
