The wool-cellulose blend, mixed-stripe Jules scarf from Rag & Bone is a good bet for city life: The muted colors go well with both suits and jeans, and the lightweight, not-too-wide dimensions make it well equipped to handle sudden temperature changes (such as the moment you walk into a subway car that's heated to 80 degrees). The scarf is not ostentatious, but it definitely has an edgier feel, which is great if you're adding it to a fairly conservative wardrobe or pairing it with a particularly sharp peacoat. [$150;]
