Abstract: The invention comprises a new and improved garment having pant legs which are shaped at the inseam so as to conform to the natural anatomical shape of the thigh. The front and back of the pant leg assume difference curvatures such that when they are sewn to a seamless crotch piece such as the one disclosed in U.S. Pat. No. 4,371,989, the garment will not rise up or bind on the wearer when the wearer sits, bends, walks or performs any other physical motion.

Abstract: A garment having a seamless crotch is described. The seamless crotch of the present invention may be used in conventional pants, such as dress pants and jeans, as well as in shorts. In conventionally lengthed pants, an essentially curved diamond-shaped crotch piece with concave edges and long tapering sections which extend down the insides of the legs of the garment is sewn into the garment. Forces generated by the assumption of a sitting position or by the raising of a leg of the wearer of the garment which would otherwise cause the garment to ride up the crotch are redirected in the area of the crotch. In the crotch piece there is no center seam along the crotch and the seams of the crotch piece curved in directions becoming transverse through the crotch so that the garment therefore does not ride up the crotch. In another embodiment a pair of shorts is described in which the crotch piece is truncated.
