A pant-like, prefastened, refastenable , disposable absorbent article includes a pair of fasteners which provide refastenable side seams and at least one waist size adjustment means. The prefastened absorbent article defines a pair of laterally opposed side edges and a pair of longitudinally opposed waist edges. The fasteners are permanently attached to the side edges of one of the waist edges and engage the side edges of the opposed waist edges to form the refastenable side seams defining a waist opening and a pair of leg openings in the prefastened absorbent article. The fasteners are further configured to provide a waist size adjustment means. The waist size adjustment means allows the wearer or the caregiver to reduce or increase the waist perimeter dimension of the prefastened absorbent article to conform the article to the wearer's body after the absorbent article is positioned on the wearer by releasably engaging the waist size adjustment means to the exterior surface of the prefastened absorbent article.
