Have you ever seen a beautiful, flowy top in a store and thought, “I wish I could make that”? A swing tunic is one of those perfect pieces of clothing. It’s comfortable, stylish, and looks great on everyone. The way it moves and drapes is just lovely.
You might think that a custom tunic with special panels is too hard to make. But I’m here to tell you a little secret: it’s easier than you think! With a few simple steps, you can create a gorgeous tunic that fits you perfectly.
This guide will show you how to sew a swing tunic from start to finish. We’ll draft the pattern, cut the fabric, and piece it all together. Let’s get our scissors ready and make something beautiful.
Getting Your Supplies Ready
Before we start sewing, let’s gather everything we need. Choosing the right fabric is the most fun part! The original design uses Georgette, which is a wonderful choice. It’s lightweight and creates a beautiful, flowing look. You could also use other light fabrics like cotton lawn or rayon.
Here is a simple list of the tools and materials you’ll want to have on hand.
| Item | Why You Need It |
|---|---|
| Fabric | About 2-3 yards of a lightweight, flowy fabric. |
| Pattern Paper | For drawing your custom pattern pieces. |
| Measuring Tape | To take your body measurements for a perfect fit. |
| Fabric Scissors | A sharp pair makes cutting clean and easy. |
| Sewing Machine | Your trusty machine for stitching it all together. |
| Matching Thread | Choose a color that blends with your fabric. |
| Pins or Clips | To hold your fabric pieces together while you sew. |
| Ruler or Yardstick | For drawing straight lines on your pattern paper. |
The First Step: Taking Your Measurements
The secret to clothing that looks amazing is a great fit. And a great fit starts with accurate measurements. Don’t worry, this part is quick and easy. Grab your measuring tape and let’s find your numbers.
You’ll want to measure a few key areas. For the bust, waist, and hips, measure around the fullest part. Keep the tape measure level but not too tight. You should be able to fit a finger underneath it. This little bit of extra space is called “ease,” and it gives you room to move comfortably.
You’ll also need to measure your shoulder width from one shoulder point to the other. Finally, decide on the length you want for your tunic and sleeves. Write all of these numbers down so you have them ready for the next step.
Drafting Your Custom Tunic Pattern
Now we get to be designers! Drafting your own pattern sounds fancy, but we’re just going to draw some simple shapes.
Making the Main Body Pattern
Start with a large piece of pattern paper. First, draw a line for the full length of your tunic, from the shoulder down to where you want it to end. Mark points along this line for your waist and hip length.
Next, at the top, mark your shoulder width and draw the neckline. A simple curved neckline works perfectly. From the shoulder, draw your armhole curve. Now, use your bust, waist, and hip measurements to mark the width of the tunic at each point. Remember to divide your measurement by four, since we are making a pattern for one-quarter of the tunic. Add about one inch for ease and another for the seam.
Finally, connect these points to create the side seam of your tunic. You’ve just drafted the main body!
How to Create the Inset Panels
The triangular panels are what give this swing tunic its special flair. These panels will be inserted into the body of the tunic, starting from the waistline.
To draft your panel, measure the distance from your waistline mark down to the bottom hem on your main pattern. This is the length of your triangle.
On another piece of paper, draw a line for this length. At the bottom, decide how wide you want the panel to be—about 8 inches is a great place to start. Mark a point that is half this width (4 inches) from the center. At the very top point of your line, make the width very narrow, less than an inch. Now, draw straight lines connecting the top point to the bottom corners. You’ve just made your triangular panel pattern!
Cutting Your Fabric

With your patterns ready, it’s time to cut your fabric. This is where your beautiful swing tunic starts to take shape. Lay your fabric out flat.
First, you’ll need to cut your main body pattern pieces. But before you do, you need to make space for the panels. Carefully cut your paper pattern vertically where you want the panels to go. You will use these new, smaller pieces to cut your fabric.
You will need to cut six of the triangular panels. You will also cut the center and side pieces for both the front and back of the tunic. Don’t forget to cut out your two sleeves. As you cut, be sure to add a half-inch seam allowance around all your pattern pieces if you haven’t already. This gives you room to stitch them together.
How to Sew a Swing Tunic: Putting It All Together
This is the moment we’ve been waiting for! It’s time to sit down at your sewing machine. We’ll assemble your tunic in a few simple steps.
Step 1: Stitching the Inset Panels
Attaching the triangular inset panels is the most important part of this DIY swing dress project. Take one side body piece and one triangular panel. Place them with the right sides of the fabric facing each other.
Here’s a great tip: start pinning and sewing from the wide bottom edge and go up to the narrow point at the waist. This makes it much easier to keep the long edges aligned and prevent puckering. Sew all six panels into the front and back body pieces.
Step 2: Assembling the Tunic
Once all your panels are in place, the rest is simple. Place the front and back tunic pieces with right sides together and sew the shoulder seams.
Next, we’ll finish the neckline. You can use a bias strip, which is a small strip of fabric cut at an angle, to create a clean and professional-looking edge around the neck.
Step 3: Finishing Your Tunic

Now you can attach the sleeves to the armholes. Then, fold the tunic along the shoulder seams and sew the long side seams, going from the sleeve cuff all the way down to the bottom hem.
The very last step is to hem the bottom of the tunic and the sleeve cuffs. Just fold the raw edge under twice and stitch it in place. Give your finished tunic a good press with an iron, and you’re done!
