I've seen men wearing necklaces, studs, and all kinds of piercings. I've got several necklaces and studs, but I always find the bracelets are the most practical accessories that one can easily put on and look good. Wearing only one is far from enough. Wearing several of them and make them look like a cuff is more fun and creative. One thing to keep in mind is that all the bracelets have to be in some kind of consistency and organized in certain order. From bottom to top, I have Dior Homme buckle style, another Dior Homme plastic cuff, Burberry Studded leather Bracelet, and Bvlgari. The rule of thumb is to stick with same or similar color and to find one that accentuate the whole idea. Mine is the Bvlgari.
An easier way is to buy a wrapped around style bracelet that will help you do the work! The Hermes Hapi 3 MM shown at the top has been on my drooping list for a long time.
