US Patent 7377834 Shaping pant

A shaping pant is made of tailored inner and outer layers of elastic clot, which are sewn together by using sewing machines; the shaping pant includes a front, a bottom, and a rear; the rear has a single-layer gathering portion at a middle thereof, which is substantially in the shape of a heart, curving and symmetric about a central line of the shaping pant; the single-layer gathering portion is sewn in position at edges thereof; therefore, air will travel through the single-layer gathering portion easily, and the wearer's butt will be lifted and shaped, looking rounder.
