Cate Blanchett at Serpentine Summer Party 2025

At long last, someone has finally nailed the mermaidcore brief: Cate Blanchett. Today, for the Serpentine Gallery Summer Party in London, the actor wore the seashell-embellished corset from Dilara Findikoglu’s fall 2025 collection.

We’re used to mermaidcore having a Y2K, H2O: Just Add Water flavor: iridescent eyeshadow, beachy hair, paillette-covered tank tops, and flowing skirts. But with her collar of spiked shells, the corset takes on an almost menacing, armor-like meaning. She isn’t Princess Ariel, but a siren who will lure men to their deaths.
