A disposable absorbent article has at least one first fastening component disposed in a first waist region and at least one second fastening component disposed in an opposite second waist region. The fastening components are adapted to releasably engage one another and at least one of the fastening components comprises primary and secondary regions that have different releasable engagement properties. Together the fastening components define a refastenable, variable-location seam having a main refastenable attachment zone providing a basic level of securement and an enhanced refastenable attachment zone providing an augmented level of securement.
