Which belt size shell i order ? 
Belts are sized in centimeters. In order to determine your Silver Ostrich belt size, we recommend measuring one of your own belts from the base of the tongue to the hole you use most.
You can also measure your waist circumference at the point where you normally position your belts.
For example, if your waist measures 85 cm, your Silver Ostrich belt size would be 85.
