A wearable article comprising a main body and an elastic belt comprising a front belt and a back belt, the main body being continuous with the front belt and the back belt, and transverse edges of the front belt and the back belt are joined to form laterally opposed side seams such that a waist opening and two leg openings are formed; wherein each of the front belt and back belt are formed by an inner sheet, an outer sheet, and a plurality of elastic bodies sandwiched therebetween; wherein at least some of the elastic bodies run in a transverse direction substantially parallel to each other; wherein, as measured according to a Material Circumference Measurement and a Whole Article Force Measurement as set forth herein, a Belt Utilization is 92%, and a Fit Circumference Force is greater than 2.0N; wherein an entire length of each of the transverse edges of the front belt is seamed with less than an entire length of a corresponding one of the transverse edges of the back belt to define a seam length LS that is the same for each seam; wherein the front and back belts are each divided into four zones extending in the transverse direction and each zone being defined by its location from a distal edge to a proximal edge relative to the percentage of the seam length LS wherein: 0-25% is a waist zone, 25-50% is a distal tummy zone, 50-85% is a proximal tummy zone, and 85-100% is a leg zone; and wherein a tensile stress of the front proximal tummy zone is higher than a tensile stress of any other zone, and no less than 200% of a tensile stress of the front distal tummy zone.
