Wearing the tennis bracelet properly can make or break your outfit. A tennis bracelet should not be too tight, nor too loose. When you can fit one finger between the bracelet and your wrist, it’s a perfect size. A diamond tennis bracelet is often worn on the left wrist. That’s because most people are right-handed and therefore use their left handless. Lesser usage means a smaller change to damage the bracelet. But if you’re left-handed, you may consider wearing the tennis bracelet on your right wrist.
