If your hips are not full enough for your tastes, there are many products sold today that can be worn under clothing to create the illusion of a curvier figure. However, these fake hips are expensive. As an alternative, make your own at home fairly easily and customize them to the size and shape you want. They can also be used as part of a costume.
Select a mannequin or other form with proportions that match yours. If you are making these for another person, you can work directly on their body as long as you are careful when sewing.
Pull the legs of a 2-part spandex bodysuit over the legs of the mannequin.
Pull a second set of spandex bodysuit pants over the first. This second set should be the same size as the first.
Sew the two bodysuits together three inches above each knee using a back stitch.
Unroll the cotton or polyester batting. Use scissors to cut the batting into 4-inch-wide strips.
Apply a layer of fabric glue inside the two bodysuits on the right side. Then place the batting against the glue. Layer the batting to achieve the desired thickness, with fabric glue in between layers to hold them together. The stuffing should be thin around the thighs and become thicker as it covers the hips.
Step back frequently as you stuff the hips to view your work from a distance. This will help you to ensure the two sides are even. Inspect them from all sides, not just the front. When done stuffing, apply another layer of fabric glue inside the two bodysuits on the left side and press the top layer of batting against it.
Sew the top edges of the bodysuits together at the waist with a blanket stitch.
Cut off the excess spandex below the knees if desired.
Wear the fake hips under pants, a dress or other clothing. Loose clothing works best, as it will not compress the cotton batting as much.
