Abstract: A shaping undergarment generally includes a front panel, a rear panel joined to the front panel, thereby forming an undergarment having a waist opening, a first leg opening, and a second leg opening, and a substantially circular, centrally-located aperture formed in the rear panel and shaped to encircle a wearer's buttocks. The aperture is defined by an edge. The edge is reinforced to preserve the substantially-circular shape of the aperture when the undergarment is worn, thereby providing uplifting support to the wearer's buttocks. Reinforcement may be provided by increasing the thickness of the edge relative to the remainder of the undergarment, as by providing a multi-layered hem, a knitted in welt, or by attaching a band to the edge. As the undergarment contracts when worn, it will tend to uplift the wearer's buttocks, and the aperture will permit the buttocks to protrude, thereby preserving a natural, rounded appearance.

Abstract: An undergarment has a front panel and back panel connected to one another and having a pair of leg openings. The back panel has a central aperture that provides uplifting support, but does not flatten the buttocks. The undergarment provides support, but allows the nature shape of the wearer's figure.
