The Herring Westminster belt is 35mm wide and hand made in Northampton using black calf leather to compliment our shoes. IMPORTANT - We recommend that you measure the distance from the tip of the buckle to the hole you currently use on a well fitting belt and order that size.Do not worry if the belt you receive is marked with a different size to the size you ordered. We measure every belt and will choose the size that is the closest match to your order, regardless of the marked size. Our belts will measure your size from the tip of the buckle to the middle of the punched holes or as close as we can get.
