Meet Coralie, a women's Halloween costume built around a dark siren look. A sequin-fronted, corset-style bodice leads into a shimmering scale-print skirt that flares into a full fishtail hem, so the mermaid silhouette reads clearly from across the room.

The bodice is shaped with structured panels and finished with a soft frill of tulle at the neckline, while sheer net flutter sleeves and a net peplum add movement as you walk. The skirt stays fitted through the hips, then opens below the knee into a floor-sweeping finish with a curved split at the front. It suits anyone who wants a glamorous, slightly villainous character for Halloween parties, themed events and adult costume nights. It also teams easily with a pirate costume for couples or group Halloween costumes.
