For accurate measurement of your bracelet size follow the simple steps below: 1. Measure the circumference of your wrist by wrapping a flexible tape measure around your wrist at a point just below the wrist bone. Then read off and record the measurement. 2. Alternatively wrap a thin strip of paper around your wrist just below the wrist bone and mark the paper where it overlaps with a pencil. Then measure the paper strip up to the pencil mark with a ruler and record the measurement. 3. Either of these two methods will give you an accurate measurement for the circumference of your wrist, to which you need to add some margin to your fitting style. We suggest doing a comfort fit if you don't have favorite style. * COMFORT FIT : Add 2cm to your wrist size * SNUG FIT : Add 1cm to your wrist size * LOOSE FIT : Add 3cm to your wrist size ** The size option is not mean the entire length from end to end but circumference on the wearing of bracelet **
