Sleek and streamlined are good goals when it comes to a wallet these days. As your wardrobe matures, so should your accessories. Thankfully, there is a wide range of well-crafted leather goods from makers big and small now. We like the card cases—simple sleeves that can discreetly store a few cards and a folded bill or two. They are ideal for slimmer pants or tucking into a jacket pocket. But if you require a little more storage, there are low-profile billfolds from such makers as Maxx & Unicorn and Ghurka that offer plenty of room for all your cards and cash while not overstuffing your pockets. Just make sure to invest in a quality brand—a good wallet can easily last you a decade.
