The Onyx Scarf-Tie Halter Maxi
Real Life Fit & Feel
The Onyx Scarf-Tie Halter Maxi
The Onyx Maxi redefines the classic black dress with a touch of sculptural artistry. Designed in a rich, deep black with a subtle ribbed texture, this dress features a plunging V-halter neckline that elongates the torso. The defining feature is the integrated scarf-tie detail at the neck—a fluid element that can be knotted for a structured look or left to drape effortlessly like a built-in accessory.
The drama continues at the back, where the halter straps meet in a bold, knotted detail that trails down the open back, creating stunning movement as you walk. Crafted from a soft polyester-cotton blend, it offers the comfort of a knit with the elegance of an evening gown.
