How do I find the right size?
WITH THE TAPE MEASURE
The basis is your wrist circumference - measured not too tight, but not too loose either. Simply place the tape measure around your wrist to determine the measurement.
ALREADY EXISTING BANGLE
If measuring is not possible, there may be an "old bangle" where the inner circumference (including the opening) can be determined, or a watch strap that provides information about the measurement you are looking for.
WITH THE RULER
If you don't have a tape measure, take a thread, wrap it around your wrist and cut it in the right place. Then you can determine the length with a ruler.
