Sports garment for shaping female buttocks and hips, including: rear part covering buttocks except their upper terminal portion, front part at least partially covering the abdomen, and waist part covering at least buttocks terminal upper portion. The rear part includes two rear elements; each including: first portions to cover: buttocks lower terminal portion, buttocks lateral portion, and hips portion; and second portions to cover: buttocks central portion and lower central portion at the garment rear fork. The rear part includes an insert increasing elastic modulus and/or tenacity of the rear part first portions relative to second portions. Lateral edges of two rear part rear elements connect along a central rear seam positioned on the buttocks intergluteal cleft; before sewing together, the lateral edges have rectilinear shape in plan view, facilitating seam insertion into the intergluteal cleft and adherence of the two elements to buttocks when wearing pants.
