A wearing article having a chassis bent in a crotch region. A diaper is folded along an imaginary lateral center line so that front and rear waist regions are in contact with each other and so that front and rear upper end edges in the regions substantially have the same level with each other. In such a folded state, first folds extending in the longitudinal direction are defined in portions of gasket cuffs which are biased toward the front waist region relative to the imaginary lateral center line. The first folds are defined along lateral edges of core of a liquid absorbent structure, and the gasket cuffs being located outboard of the lateral edges are folded along the first folds onto a garment-facing side of an outer sheet. Second folds which extend in the longitudinal direction are formed in containment cuffs. The second folds are lying on a side closer to the front waist region in relation to the imaginary lateral center line, and folded distal ends are expanded and folded to the garment-facing side of the outer sheet.
