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 the transversely opposed side 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 is 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 the transverse direction substantially parallel to each other; wherein each front belt and back belt have transversely continuous proximal and distal end edges, the proximal edge being located closer than the distal edge relative to a transverse center axis of the article; wherein an entire length of the transverse edge of the front belt is seamed with less than an entire length of the transverse edge of the back belt to define a seam length LS; wherein the front and back belts are each divided into 4 zones extending in the transverse direction and each zone being defined by its location from the distal edge to the 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 belt leg zone is no more than 50% of a tensile stress of the front belt proximal tummy zone, and the tensile stress of the back belt leg zone is no more than 100% of the tensile stress of the back belt proximal tummy zone.
