DIY jumpsuit sewing pattern

1. Create the jumpsuit sewing pattern

Fold your fabric in half, right-side facing in. Measure your hip circumference, add 5 centimeters (2 inches) to that measurement and divide the total in two. Mark that measurement on your fabric, measuring from the open edge.


Now, place a small mark on the fabric halfway across the hip width.

Making the jumpsuit sewing pattern

Fold a t-shirt in half lengthwise and place the folded edge at the last hip mark you just made (the midline). Lay the t-shirt so that the bottom of the neckline lines up with the top of your fabric and mark the waistline position on your fabric.


To allow for some looseness in the jumpsuit, move the shirt and pants over about 5 centimeters (2 inches) from the midline. They will now lie between the edge of your fabric and the midline mark.


Fold in the sleeve of your t-shirt, then trace around the entire t-shirt and pants, so you have a pattern for the left side of your jumpsuit.

Creating the right side of the pattern

Now, flip the top and the pants over and lay them on the right of the midline mark, so you can trace the mirror image of the left side of the jumpsuit for the right side.


Cut the complete pattern from the fabric. You will now have two full pieces.

Pinning the DIY jumpsuit bodice

2. Sew the jumpsuit bodice

Unfold both pieces and, with right sides facing, pin them together from the waist to the crotch on both sides. Sew the seams from waist to crotch using a zigzag stitch.


Tip: If your fabric has a design, like stripes, try to line up the pattern as best as you can.

Marking the waistline with tailor's chalk

Mark the waistline across the fabric.

Folding and pinning the top edges

Fold the top edge of the DIY jumpsuit over twice. Pin in place and sew the top hem.

Shirring the bodice with elastic thread

Now, switch the regular sewing thread in your sewing machine to the elastic thread. Test for the right tension of elastic thread using a scrap piece of material until you are satisfied with the amount of shirring.


Sew horizontal lines from the top of your jumpsuit to the waist, keeping the rows close together for good shirring in the whole jumpsuit bodice.

Pinning the DIY jumpsuit legs

3. Sew the jumpsuit legs

Return the regular sewing thread to your sewing machine. With the jumpsuit inside out, pin the inside of the jumpsuit legs together and sew with a zigzag stitch. 

Trimming the excess fabric from the seam

Trim the excess seam allowance from the inside of the pant legs.

Folding the pant leg hems and pinning

Fold up the pant leg hems and sew the hems.

Adding elastic to the top of the bodice

4. Fit the very top of the jumpsuit

Try on the jumpsuit, and if the top of the bodice doesn’t feel secure enough, and a wider piece of elastic to the very top.


Measure your body to determine the length of elastic you will need and cut that length. Pin the elastic in four places evenly around the top of your DIY jumpsuit.

Sewing the elastic to the top of the bodice

Sew the top elastic in place by pulling it straight so it sews smoothly onto the fabric.

Measuring the DIY jumpsuit straps

5. Make the jumpsuit straps

Cut two strips of fabric measuring 5 centimeters x 30 centimeters (2 inches x 12 inches) each. 

Folding the straps in half lengthways

Fold each strap in half with right sides facing in and sew the long open edge closed.

Attaching the straps to the jumpsuit

Turn the straps right side out and pin the short edges in place on the jumpsuit. Try on your DIY jumpsuit to check the size and positioning of the straps and adjust as necessary. Then, sew the straps in place.

Making a belt for the DIY jumpsuit

6. Make a belt for the jumpsuit

If you have more fabric, cut a belt piece measuring 1.6 meters x 10 centimeters (63 inches x 4 inches), or an appropriate length for your waist. If you prefer to have rounded corners on the ends of your belt, cut the corners now. 

Folding the belt in half lengthways

Fold your jumpsuit belt in half lengthwise and sew the open long edge. Turn the belt right-side out and topstitch the entire belt, including the short edges.
