Abstract: Pants that comprise a pair of intermediate body sheets, positioned in plane symmetry to each other and respectively contoured by upper, lower, inner and outer edges, and a pair of lateral body sheets also positioned outside the respective intermediate body sheets and respectively contoured also by upper, lower, inner and outer edges. Each of the intermediate body sheets is formed between the inner and outer edges with an arcuate cutout extending convexly from the upper edge, toward the lower edge the intermediate body sheets being put flat and sealed together along a sealing line defined by the cutouts but leaving a narrow marginal edge free. The intermediate body sheets and the lateral body sheets are placed flat and sealed together along sealing lines defined by inner and outer edges thereof, leaving narrow marginal regions free outside the inner and outer edges.
