First order was a size 36 and was 5" under, ordered a size 38 and was 3" under and didn't match any belt size in my closet. My size 38 was getting too big due to weight loss so I ordered a small 36 and it was way out of range and 38 was also too small. All of my current belts fit just perfectly, anyone who has ever made these belts has not been able to change their measurement system to US measurements. I am returning size 38.
