Abstract: Panties, briefs or like underwear includes a front piece 2 for covering lower abdomen, a rear piece 3 for covering buttocks and a connector piece 4 interconnecting the front piece 2 and the rear piece 3 for covering the crotch. The rear piece 3 is stitched at its lower end to the connector piece 4 while being stretched most greatly on the center line of the rear piece 3 and to a progressively lesser extent from the center line toward the opposite sides thereof. As a result, an elongated depression 6 extending vertically is formed on the center line of the rear piece 3 in conformity with the gluteal cleft between the buttocks. On the opposite sides of the depression 6, the rear piece 3 has rounded portions in conformity with the bulges of the buttocks.
