Bangles or cuffs are great for everyday wear. They are small and normally tighter to your wrist. Some people prefer one over the other for comfort, so choose whichever suits your. Most thin bangles are sold in sets - getting you more bang for your buck. Shop bracelet 3 and bracelet 4. (bracelet 3 is no longer available; here is an alternative.)
Lastly, arm parties have been the rage the past couple of years. These two pieces I consider essentials to taking your arm party to VIP level. They are made to layer and extremely versatile. In fact, I dare you to try them together with a bangle or a cuff for an every day, casual look. Shop bracelet 5 and bracelet 6. (bracelet 6 is no longer available but here is another favorite.)
