If the bracelet is a gift:
If the bracelet you are buying is a present and you don’t know the actual wrist size of the person who will receive the bracelet, you can measure the size of another bracelet the person already has. Lay this bracelet flat on the table and measure it with a ruler. The size you just measured is the bracelet size, which is always a bit bigger than the actual wrist size. It is very important that you include "bracelet size" in the wrist size note at checkout.
