Abstract
An absorbent article such as a diaper comprising an acquisition layer with one or more longitudinally-extending stretch openings is provided. The stretch openings may be obtained by slitting and stretching an acquisition layer material. The topsheet forms recesses at the wearer-facing surface of the absorbent article as it folds inside the stretch openings. The stretch openings may provide a three dimensional profile on the wearer-facing side of the absorbent article in a simple and cost effective manner.
