If you do not know the size of your wrist, it’s quite simple: take a yard of a dressmaker or if you do not have one a string. The size of the wrist is taken after the wrist bone, with the meter you easily know your circumference, for the string, once the turn is done, put it on a graduated ruler to know your wrist size. When ordering on the website, you will find a size chart (graduated every centimeter) you can then tell me in the comment section (which is in your shopping cart) if you prefer to wear your bracelet loos or rather adjusted. If you order at an Ausica stand during a fair, your wrist size will be measured by our representatives. For all orders by mail, please indicate the size on a paper slipped into your envelope.
