The invention relates to an absorbent, disposable article, preferably a diaper, having a backsheet and a topsheet comprising a first waist region, a second waist region, and a crotch region interposed there between, a longitudinal axis, and an opening, which provides a passageway to a primary void space for receiving bodily exudates therein, positioned between the topsheet and the backsheet, whereby the opening is positioned in at least the crotch region along the longitudinal axis whereby the topsheet is elasticated and whereby the article has a shortened article portion, as defined herein, which has a shortened article length L, a stretched shortened article length Ls and a contracted shortened article length Lc, whereby the article and/ or its topsheet has a specific ratio of Lc to Ls. The article preferably has a slit opening with on each side elastic regions, preferably in the shape of an X and preferably making an angle with the adjacent topsheet and thereby bending away from the void space underneath the topsheet.
