About

Mermaidcore broke through in early 2023, propelled by the press cycle around Disney's live-action Little Mermaid and a Pinterest-reported 614% spike in 'mermaid' searches. The wardrobe trades on iridescence and aquatic motifs: fish-scale-sequined dresses, shell-strung necklaces, pearl-trimmed everything, sheer chiffon in seafoam and lavender, baroque pearl headpieces. Designers including Versace (with the chainmail mini-dress), Blumarine, Conner Ives and Coperni were credited with pushing the silhouette through Spring 2023 runways. Beauty followed: pearlescent eyeshadow, dewy aqua-blue liner, glossed lips. The hashtag amassed 14.5 billion TikTok views.

Not Coastal Grandmother — Mermaidcore is fantasy and shimmer (sequins, shells, sirens); Coastal Grandmother is matte and grounded (linen, cashmere, real beach).
