Making your own ballet leotard ensures that you'll have the perfect fit, and allows you to customize to suit your style. Ballet leotards are typically in soft pink or black, but you can create one in any color for fun. Although prior sewing experience is not necessary, use a pattern to achieve symmetry. This project is for a basic sleeveless design, which will only require two pattern pieces. Once you have a pattern and fabric -- choose one with at least 70 percent four-way stretch, such as a Lycra blend -- you are ready to begin your project.
Determine your size by measuring you waist, hips and bust. Match your measurements to the sizing guide on the pattern envelope to determine your size.
Lay out your fabric on a flat work surface. Iron out any wrinkles on your pattern pieces to ensure precise lines while cutting your fabric. Pin the front side and back side pattern pieces to the fabric. Cut the fabric according to your pattern. Put the two pieces on top of one another, with the two right sides of the fabric facing each other. Pin the two sides together along the edges of the fabric.
Sew the two sides of the leotard together with your sewing machine, being careful not to sew over the pins. The stitches should be close to the edge. Remove the sewing pins as you go.
Try the leotard on. It should fit adequately, but if you are not happy with the fit use a seam ripper to remove the stitches carefully. Now you can sew again with a larger seam allowance. Once you are satisfied with the fit, take the leotard off and sew the final hem lines.
