I’ve had lots of requests for a bodysuit tutorial, so here it is! Follow along and I’ll show you how to make a DIY bodysuit pattern, and how to sew the bodysuit.


You will love the final look of this DIY bodysuit, and like all bodysuits, it will never come untucked, so you will always look polished and professional when you’re wearing it.

Tools and materials:

  • Bodysuit (as a pattern)
  • Good-fitting t-shirt
  • Underwear
  • 1 yard of stretch fabric
  • Scissors
  • Sewing pins
  • Tape measure
  • Fabric chalk
  • Snap fasteners
  • Sewing needle
  • Thread
  • Sewing machine
How to make a DIY bodysuit pattern

1. Make your DIY bodysuit pattern

If you have a bodysuit already, then you can simply trace it to make your pattern. But if you don’t have a bodysuit, you can use a good-fitting t-shirt and a pair of underwear as your bodysuit pattern template.

Tracing a t-shirt and underwear

Simply place the t-shirt and underwear on a single layer of fabric and cut out the outline.

Folding the DIY bodysuit pattern

Fold the fabric pattern piece in half lengthwise and trim the edges so it’s completely symmetrical.

Cutting out the DIY bodysuit pattern again

Now place that pattern piece on your fabric and cut out the pattern again. You should now have two pieces – a front and a back. 

Making the front leg hole narrower

Use fabric chalk to mark a narrower leg hole on the front piece, and when you are satisfied with the shape, cut the leg hole on the front piece only.

Cutting the bodysuit neckline

2. Make the bodysuit neckline

With the front piece folded in half lengthwise, draw a V-shape from the shoulder to your desired neckline length. Cut out the V-shape.

Making a snip at the bottom of the V

Make one small snip at the bottom of the V.

How to sew a bodysuit

3. Sew the bodysuit bodice

With right sides facing, pin the front of the bodysuit to the back along the sides and shoulders. Do not pin the bottom. Sew the side and shoulder seams.

Tracing the bodysuit sleeves

 4. Make the bodysuit sleeves

Fold the fabric and cut out bodysuit sleeves using your t-shirt as a pattern. Place the outside edge of the t-shirt sleeve along the fold of your fabric. Use that sleeve as your pattern to cut a second sleeve.

Sew the sleeves into the bodysuit armholes.

Hemming the leg holes

5. Hem the leg holes and sleeves

Now, fold in and pin a hem at the bottom of the bodysuit and sew the hem close to the edge using a zigzag stitch.

This is how it should look.


Do the same to hem the bottom of the sleeves.

Making a neckband for the bodysuit

6. Make the bodysuit neckband

Now measure the length of the V-neck along both sides and the back. Mine was 55½ centimeters (21.85 inches) in total.

Measuring the neckband

With fabric folded, cut an 8-centimeter (3.15-inch)-wide strip of fabric that is half the total neck length long, with the short end on the fold.

Make your own bodysuit

On the open short edge, draw a V-shape from each outer corner to the middle.

Then fold the piece in half lengthwise and cut out the V so it is symmetrical.

Unfold the strip once and pin the V on both ends together. Then sew with a ¼-inch seam allowance

How to make a bodysuit step by step

Make a small snip at the bottom of that V, just like you did with the neckline, being careful to cut only in the seam allowance.

Pressing the seam allowance

Press the seam allowance open and then fold the neckband in half.

Pining the neckband

Pin the neckband edges together and then sew along the edge of the just the V-shape. Then trim the raw edges of the V.

Attaching the neckband

Turn the bodysuit right-side-out. With right sides facing, pin the neckband to the bodysuit neckline just at the V-shape, lining up the raw edges and the centers of the Vs. Sew the neckband to the neckline from the bottom of the V up a few inches on one side only.

Pinning the neckband in place

Turn the bodysuit inside-out and pin the rest of the neckband in place. Sew the neckband in place using a straight or zigzag stitch. Then top stich to get a professional finish.

Finished neckline

This is how your finished neckline will look.

Adding snap fastenings to the crotch

7. Add snaps to the crotch

Hand-sew the snap fasteners in place at the crotch of the bodysuit.
