The article comprises a backsheet (28), a liquid-permeable topsheet (26) and an absorbent body (30) sandwiched between the backsheet (28) and the topsheet (26). At least one pair of wing-panels (42, 42) are operatively joined to the intermediate portion (76) of the article (20). Each wing-panel (42, 42) extends laterally from at least one corresponding lateral side edge region, and each wing-panel (42, 42) is configured to wrap about a wearer's undergarment. A panel fastener (44, 44a) can be joined to each wing-panel (42, 42), with each panel fastener (44, 44a) configured to operatively secure its corresponding wing-panel (42, 42) about the undergarment.
