Extended data

There are generally three kinds of belts, high waist, middle waist and low slung belt. Generally, young girls have the lowest waist and older girls have the highest waist. The belt has no international size. It is customary to remember that sizes are the same as clothes, which are divided into xs, s, m, l, xl, xxl and so on. Before buying a belt, make sure it is tied at a high waist, a middle waist or a low waist. The actual size of the belt should be 2 inches larger than the size of the required parts.
