- 1). Use the first pillow case to cut out the two front pieces of the bustier. Each piece should be long enough to reach from the top of your bust to your hips and as wide as the widest part of your torso.

- 4). Lay both front fabric pieces on top of each other, right sides together. Sew them together, all the way around, leaving a 1-inch opening in the seam.
- 5). Turn the front piece right side out, using the 1-inch opening. Sew the 1-inch opening closed.

- 8). Lay the two back pieces of fabric on top of each other, right sides together. Sew the two pieces of fabric together all the way around, leaving a 1-inch opening in the seam.
