A first body portion is also attached to the waistband via at least one second fastening means in such a way that the article assumes a pant diaper form A. The waistband comprises a reception surface and a perforation which allows it to be separated into first and second belt portions, whereby at least a part of the reception surface is located on each belt portion, such that the article assumes a belt diaper form (B). The first belt portion comprises at least one first fastening means.
