Dark, daring and impossibly sleek, the black sequin Sleeveless Square Neck Mermaid Maxi Dress is the kind of gown that makes a room go quiet. The structured square neckline frames the décolletage with couture-level precision, while the sequin stretch mesh clings to every curve in a liquid, second-skin finish that flows into a dramatic mermaid hem. Black sequin has never looked this refined, this sculptural, this effortlessly powerful.
