Seapunk is a 2010s internet aesthetic of dolphins, aquatic imagery, and 90s web culture, born on Tumblr around 2011 as an ironic blend of ocean and digital themes. Ocean-toned aqua and green hair carries it. Iridescent or holographic fabrics cover the garments. Mermaid-scale prints and anchor motifs run across them, with shell accessories and deep sea-inspired layering.
