The classic staple to complete the perfect leather uniform, the Sam Browne shoulder strap in plan belt leather. Fully adjustable, but you need to allow for the 2 Sliding D belt attachments ($7.95 each, not included).
We recommend you measure yourself by putting on your pant of jean with a belt, then place a measuring tape on the left belt loop, over the right shoulder to the left side of your center belt loop on the back of your pants. Once you have that measurement, choose the belt with the next smaller size. For example, if you measured yourself to 46" with the measuring tape, choose a 36/38. If you measured 52", choose a belt size 40/42. Adding the 2 sliding D belt attachments will make up the difference.
