Joshua McKinley for Johnathan Kayne Collection 3215S

Make a head-turning entrance in the Johnathan Kayne 3215 from the Joshua McKinley Collection — a fitted, floor-length purple beaded mermaid prom dress crafted in shiny stretch lycra. A sweetheart neckline and beaded spaghetti straps frame a sculpted corset bodice, while ruched waist detailing flatters every curve before the gown flares into a dramatic mermaid skirt and sweep train. A mid-open back with secure zip closure completes this red-carpet-worthy look, making style 3215 a stunning choice for prom 2026, pageants, galas, and special evening occasions.
