Abstract: A relief opening for a pair of women's pants, the opening formed in a center relief panel joining leg portions of the pants in at least a downward-facing central portion of the crotch area. The relief panel includes two separable and overlapping layers or flaps of fabric over at least a center portion of the panel in the downward-facing central portion of the crotch region of the panel. Each separable flap has an unattached, reinforced relief seam or edge facing and adjacent the opposite leg, each relief seam over- or under-lapping the other separable flap. At rest, the relief seams are positioned on opposite sides of a centerline of the center relief panel, and the flaps are closed, such that the center portion of the panel generally appears and functions as a single, solid, closed panel from at least the front and back of the pants.
