Yes, specific fabrics such as satin, chiffon, tulle, organza, and pearl-like or sheer lightweight materials are central to the mermaid-core fashion trend for 2025. These fabrics evoke an ethereal, ocean-inspired aesthetic characteristic of the trend.
The mermaid-core fashion trend, which continues to be popular into 2025, emphasizes fabrics that create a dreamy, aquatic-inspired look. According to People, satin slip dresses made from washable silk are a key fabric, offering a smooth, water-like drape that enhances the mermaid aesthetic without appearing too literal. This aligns with the trend's focus on shiny, fluid textures that mimic the shimmer of mermaid scales and water surfaces [1].

Further, Seventeen emphasizes the use of fabrics that resemble seashells or pearls, reinforcing the oceanic theme, and suggests that these materials contribute to the trend's whimsical, fantasy-inspired aesthetic [1].
Overall, the fabrics defining mermaid-core for 2025 are those that evoke fluidity, shimmer, and delicacy—primarily satin, chiffon, tulle, organza, and pearl-like or sheer lightweight textiles—creating a look that is both ethereal and reminiscent of the sea.
