Using this belt is super easy. Just pass it through the belt loops of your dress and fasten it with the buckle. When choosing the right size, measure your waist and pick the appropriate length. For the 65cm belt, it's great for waists between 63 - 80cm, and the 75cm one fits waists from 75 - 105cm. To keep it looking good, avoid contact with sharp objects that could scratch the metal parts. Clean it gently with a soft cloth. Store it in a dry place to prevent rusting on the metal and alloy components. This way, your belt will stay a stylish accessory for a long time.
