A method of making disposable absorbent articles which include an outer cover, an absorbent chassis and an adjustable belt includes providing two continuous, laterally spaced apart ribbons of fastener material and attaching belt segments between and to the ribbons of fastener material at longitudinally spaced apart locations in a continuous ladder type configuration. Two continuous, laterally spaced apart ribbons of belt loop material are also provided inward from and adjacent to each of the ribbons of fastener material. The ribbons of fastener material and ribbons of belt loop material are selectively cut into discrete adjustable belts each of which defines one of the belt segments, a pair of laterally spaced apart fasteners attached to opposite end portions of the belt segment, and a pair of laterally spaced apart belt loops. The longitudinal ends of the belt loops of each of the adjustable belts are attached to a waist region of each of the absorbent articles to slidably contain the adjustable belts between the longitudinal ends of the belt loops. The fasteners on the adjustable belts are configured to releasably engage an opposite waist region of the absorbent article to conform the waist regions to a wearer's body after the absorbent article has been placed on the wearer. The belt loops may include fastener material on a bodyfacing surface to provide another pair of fasteners.
