Cable knit no longer means having to date someone on the rugby team or voting Republican. And no need to dust off the penny loafers and dip into prepster chic, courtesy MJ. Marc Jacobs’s neo-preppy, 100 percent wool, cable-knit, fingerless gloves stop right below the elbow and are more urban league than Ivy League. The cozy arm warmers come in aqua, lavender, and cream. The exposed fingertips allow for an easy grip on the steering wheel of Mom’s Volvo. All in all, a very stylish way to keep warm during those autumn trips to the Cape. Move over, sweater sets. There’s a new official preppy hand look. Available online at purpleskirt.com.
