Nikki sleeveless jumpsuit sewing pattern

Nikki sleeveless jumpsuit free sewing pattern

The Nikki sleeveless was inspired by a design by brand No. 6 (although I don’t remember the year of the collection). It was designed with versatility in mind. It features a loose-fitting bodice, a round neckline, and above the knee wide-leg pants that provide both comfort and style. The jumpsuit also has side pockets for added functionality, making it practical and fashionable at the same time.

One of the best parts of sewing your own jumpsuit is the ability to customize it to your liking. You can experiment with different fabrics, colors, and patterns to make it truly your own. Add a statement belt to cinch in the waist, or embellish it with buttons, trim, or lace to make it uniquely yours. With this free pattern as a base, you have the creative freedom to tailor the jumpsuit to your personal style and create a one-of-a-kind wardrobe staple.

My pattern is made in 10 sizes from XXS to 5XL so you may find a suitable size for yourself. If you are not sure which size suits you, take a look at the measurement table before doing anything here: SIZE GUIDE.

The pattern is made using layered PDF, please check for your desired size before printing so you won’t waste your paper. I have included a first page with many details about sizing and printing, so please first read the first page and make sure you know what size you need! If you still do not know how to print a layered PDF, please check for the printing instruction in this post: PRINTING GUIDE.

You can print this using your home printer and A4/Letter paper. I calculated the printing area so that you will be able to use either type of paper to print the pattern out perfectly. Always print the first page first and check with the test square if you are printing at the right scale before you print out the whole pattern – avoid waste of ink and waste of paper, save the earth!

Some PC may print smaller than actual size even when you choose 100% scale – I don’t know why this problem exist, but my HP laptop cannot print true to size. I have to scale up to 103% to get the right size. You may need to check with your PC to see if it prints true to size, if not, scale up a bit.


You will need

  • Fabric of your choice. This pattern is made for woven fabric. It is an oversize design so you can choose to size down for a smaller fit.
  • Scissors, pencil or fabric marker, ruler, pins
  • Sewing machine/Serger or needle and thread
  • Printed pattern

How much fabric do you need for this piece of garment? To be precise, you may need to check how much fabric you need before buying. It will depend on the selected pattern size, the width, and design of the fabric you plan to use. Just to be sure, print all the paper patterns and lay them out at the width of fabric you plan to use (usually from 90 to 150 centimeters or 35 to 60 inches). Measure how much fabric you will need. Don’t forget to account for pieces that need to be cut multiple times and pieces that are cut on the fold.

Cutting instruction:

After printing out and taping all the pattern pages together, cut the patterns out and you will get the following pattern pieces:

You will see that there are 2 sets of lines on each pattern piece. The inner lines are sewing line (and you sew along these lines), and the outer lines are cutting lines (you cut the fabric along these lines, remember the folding lines where you have to fold the fabric before cutting). The distance between sewing line and cutting line is seam allowance, and it varies from point to point. For example, the side seam allowance is about 1/2 inch (1.2cm), and seam allowance at hemline is 1 inch (2.5cm). This is the reason why I do not remove the sewing lines from the pattern. Please use it as a guide to know how much seam allowance you need to give at each seam.

This piece of garment can be made lined, or unlined. If you choose to make unlined version, cut as follows:

  • Front: cut 2
  • Back: cut 2
  • Front Facing: cut 1 self + 1 fusible interfacing (on fold)
  • Back Facing: cut 2 self + 2 fusible interfacing
  • Pocket: cut 4

You can also ditch the Front and Back Facing and use bias binding to finish the neckline and armholes of this garment.

Make sure to mark all notches and other design features such as darts, pleats etc. from the pattern pieces onto your fabric. When sewing the garment, pay attention to notches, they must match up.

Sewing instruction

1. Serge/zig zag stitch the raw edge to prevent fabric from unraveling.

2. Apply fusible interfacing to Front and Back Facing pieces.

3. Attach pocket pieces to the Front and Back pieces. Instruction on how to attach side seam pocket can be found here.

4. Place corresponding side Front and Back pieces right side facing. Pin and sew the shoulder and side seams. You get two halves of the main garment.

5. Sew the inseam of the pant part.

6. Turn one half garment inside out, push into the other half. Pin the center seam from the front to the crotch to the first notch at the back. Sew to join the two halves.

8. You are going to do a all-in-one facing for the garment.

– Place the joined main garment and the joined facing pieces right side facing. Pin along the neckline. Sew the neckline. Trim and clip the seam for smoother neckline. Turn the fabric out and iron flat. You can also top stitch the seam toward the facing piece to make it stay flat inside.

– Lay the garment flat, facing side up, and tightly roll right side of the garment towards the opposite edge.

Then take your left/unrolled facing armhole edge and wrap it around the roll so that it meets the left armhole edge of the garment. Basically, you are enclosing the right side of the garment between the left facing and left garment fabrics like a burrito.

– Align the raw edges of your left armhole and pin the two right sides together.

Sew the armhole seam right sides together at your usual seam allowance taking care not to catch the rolled up fabric. Trim and clip your seam allowance.

– Gently pull the rolled bodice right side out.

9. Pin and sew the side seams of the garment from the lower pant part to the armhole and facing.

10. Attach zipper to the back of the garment.

11. Hem the pant legs.

Although the all in one facing may be a bit tricky, you will find this project not too difficult.
