  • Patent number: 5896581
    Abstract: A unitary garment with a modified and improved drop-seat which is not overtly detectable by the casual observer. The rear portion of the garment is constructed with two plies of fabric. The inner ply contains a teardrop-shaped aperture (12) bounded by elastic around the perimeter. The outer ply incorporates a trapezoidal-shaped lappet (20) with elasticized sides. The combination of these two innovations enables a heretofore unachievable style line which closely conforms to body contours. Due to the elastic tension around the perimeter the aperture is relatively static in relation to the buttocks and upper thigh thereby allowing the wearer freedom of movement during toilet and personal hygiene activities without fear of inadvertently wetting or soiling the garment. Multiple styling embodiments are possible (e.g., jumpsuit, culottes, shorts, formal-, casual-, sports-wear, et al).
