Sailing stripes are going full steam ahead. Coco Chanel famously employed the motif in her day, and her enduring luxury label is at it again with a new take on its iconic quilted handbag. The traditional stripe also surfaced on a canvas slip-on from Mother of Pearl and a maritime tote from Valentino. For the ultraluxe swashbuckler, a bold streak of white on a rabbit fur stole from Marc Jacobs, wool sweater from Chloé and tailored trousers from Vince would look just as chic at high tea as it would on the high seas. And a Verdura bracelet of pearls and sea-colored sapphires anchors any seafaring look.
