When introduced to pattern and texture, black and navy blue take on intriguing depth. Start with the modern silhouette of a boxy top and an A-line skirt: the dark navy of Stella McCartney’s scalloped-hem blouse plays beautifully against the glowing indigo florals of a Kenzo wrap skirt. Alexander McQueen’s De Manta clutch, with a shape inspired by the ray of the same name, provides a sculptural counterpoint. Fine-tune the look with any of these three standout shoes. For a minimalist complement, look to Acne’s signature Pistol boots. Snakeskin-embossed Lanvin derbies balance menswear inspiration with feminine ribbon laces. And Stella McCartney enlivens platform pumps with a faux tortoiseshell heel. It may break the color scheme, but it’s everything we love about the black and navy mix: understated and unexpected.
