The sweetheart neckline — a curved, heart-shaped cut that frames the décolletage and elongates the silhouette. At HERTROVE, our sweetheart evening gowns are crafted by luxury designers in embellished tulle, duchess satin, and silk organza. A neckline that flatters every figure — from fitted mermaid silhouettes to full ball gowns — for galas, weddings, and black-tie occasions where timeless femininity is the point.
