Provided is pants having a body-shaping function including; an elastic fabric included in the pants, and having a boundary that is partially fixed on the pants to elastically support hips of a wearer; and a hip-up band fixed on the elastic fabric to push the hips up so as to make contours of the hips more voluminous or compression bands on lower side portions of the elastic fabric in order to compress thighs of the wearer so as to make the thighs look thin, or a pair of pads having predetermined thicknesses and disposed on the elastic fabric to make the hips of the wearer look more attractive. Therefore, since the elastic fabric is integrally fixed in the pants for shaping the hips, the conventional girdle is not required. In addition, since the girdle in the pants only compresses the hips, it does not affect blood circulation around the belly, and is easily wearable. Also, the contours of the hips look more attractive due to the pads.
