Effortless, understated, and impossibly chic. The Onyx Linen Slip Mini Dress in Black is a sleek, sophisticated mini in a soft rayon-linen blend that drapes beautifully and feels luxurious against the skin. The clean scoop neckline sits elegantly on the collarbone, while thin adjustable spaghetti straps with gold-tone hardware allow for a perfectly customized fit. A discreet side zipper closure keeps the silhouette sleek and uninterrupted, while a delicate self-tie bow at the back waist adds a sweet, feminine finishing touch. Built-in shorts underneath mean you can move and style with complete confidence. Fully lined for comfort and coverage.
Style with black strappy heeled sandals and gold jewelry for a polished date night look, or pair with white sneakers and a linen blazer for an elevated everyday outfit. The perfect throw-on-and-go dress that always looks intentional.
