Patented is a wearing article comprising first and second waist regions each with a body-facing surface and a garment-facing surface. The first and second waist regions cooperate together to define a waist-opening and a crotch region extends between and cooperates with the first and second waist regions to define a pair of leg-openings. A fastening system releasably connects to the first and second waist regions. The fastening system comprises engaging fasteners respectively located on transversely opposite side edges of the first waist region and landing fasteners located on the garment-facing surface of transversely opposite side zones of the second waist region. Each of the engaging fasteners has an insert and an engaging portion while each of the landing fasteners has a pocket adapted to receive the insert and a landing portion formed on an outer surface of the pocket so that the engaging portion releasably engages the landing portion. At least one of the first and second waist regions has elastic members serving to elastically adjust a circumferential waist dimension defined by the first and second waist regions. The engaging portion releasably engages the landing portion and the insert is received in the pocket without positively and directly engaging an inner surface of the pocket. The insert, if pressed into contact with the engaging portion by a pressing force, is elastically detached from the engaging portion when the insert is relieved of the pressing force. Each of the engaging portions comprises a hook member with a plurality of hooks projecting from a backing of the hook member toward the insert.
