Hello, creative friends! Have you seen those super cool shirt jackets everywhere? They’re called “shackets,” a perfect mix between a shirt and a jacket. They are comfy, stylish, and perfect for layering. And the best part? You can totally make one yourself!
If you’ve ever thought, “I could never sew something like that,” I’m here to tell you that you absolutely can. Learning how to sew a shacket is easier than you think. Forget confusing instructions and complicated steps. We’re going to walk through this sewing tutorial together, one simple step at a time.
In this guide, I’ll show you exactly how to make your own DIY oversized shirt jacket. Get your sewing machine ready, and let’s create a beautiful piece you’ll be proud to wear.
What You’ll Need for Your Shacket Project
Before we start sewing, let’s gather our tools and materials. Having everything ready makes the whole process smooth and fun. Think of it as getting your ingredients ready before you start cooking!
Here’s a simple list of what you’ll need for your shirt jacket sewing adventure.
| Category | Items Needed | My Quick Tip |
|---|---|---|
| Fabric | 2-3 yards of medium-weight fabric like flannel, corduroy, denim, or twill. | Pre-wash and dry your fabric before you cut it! This stops it from shrinking after you’ve sewn your shacket. |
| Pattern | A shacket sewing pattern. (Like the Polina pattern or any other you like). | Read the pattern instructions first. It will tell you exactly how much fabric to buy for your size. |
| Notions | All-purpose thread that matches your fabric, buttons (usually 7-9). | Get a little extra thread, just in case. It’s always better to have more than to run out mid-project. |
| Tools | Sewing machine, fabric scissors, pins or clips, an iron, a seam ripper. | A sharp pair of scissors makes cutting so much easier. An iron is your best friend for crisp, flat seams. |
Let’s Get Sewing! Your Step-by-Step Guide

Alright, are you ready? We’re going to build this beautiful shacket piece by piece. Don’t rush—enjoy the process of watching it come together.
Step 1: Create the Front Plackets
The placket is the band of fabric down the front of the shirt where the buttons and buttonholes go. Getting this part right makes your shacket look very professional.
First, take your two front shacket pieces. Your pattern will show you where to fold the fabric to create the placket. Fold the edge over twice and press it flat with your iron. This creates a clean, sturdy edge. Once it’s folded neatly, sew a straight line down the placket to hold it in place. This is called “topstitching,” and it adds a nice, clean look. Do this for both the left and right front pieces.
Step 2: Put the Body Together
Now we’ll make the main body of your shacket. You’ll need your two front pieces and your back piece. Many patterns also have a “yoke,” which is a small panel that sits across the upper back, just below the collar. It helps the shacket fit better over your shoulders.
Lay the back piece down. If you have a yoke, sew it to the top of the back piece. Then, place the front pieces on top of the back piece with the right sides of the fabric facing each other. Line up the shoulders and the side seams. Pin them in place and sew them together. When you’re done, you’ll have something that looks like a vest!
Step 3: How to Sew a Collar
The collar is what really makes it look like a shirt jacket. This part might seem tricky, but it’s just a few simple seams. A collar is usually made of two parts: the collar itself and the “collar stand,” which is the little band it sits on.
First, sew the collar pieces together, leaving the bottom edge open. Trim the extra fabric at the corners and turn it right-side out. Use a pointy tool, like a pencil, to gently poke the corners out so they are nice and sharp. Press it flat with your iron.
Next, sew the collar stand pieces. Then, you’ll sew one edge of the collar stand to the collar. Finally, you’ll attach the whole collar unit to the neckline of your shacket. Pin it carefully, starting from the center of the back and working your way to the front. Sew it slowly to make sure it’s even.
Step 4: Add the Sleeves and Cuffs
Your shacket is really taking shape! Now it’s time for sleeves.
First, fold each sleeve in half and sew the long seam to create a tube. Next, we’ll make the cuffs. The cuff is the band at the end of the sleeve. Just like the collar, you’ll sew the cuff pieces together, turn them right-side out, and press them.
Attach the cuff to the bottom of the sleeve. Your pattern might have you make a small pleat in the sleeve fabric as you attach the cuff. This gives you a little more room to move your elbow.
Once the sleeves are ready, it’s time to set them into the armholes of the shacket body. This can feel like putting a round peg in a round hole. Turn the shacket body inside out but leave the sleeve right-side out. Slide the sleeve into the armhole, match up the seams, and pin it all the way around. Sew slowly and carefully around the circle.
Step 5: Pockets Make it a Shacket!
What’s a jacket without pockets? The big chest pockets are a classic part of the shacket style.
First, make the pocket flaps. These are the little pieces that cover the top of the pocket. Sew the flap pieces together, turn them right-side out, and press them flat.
Next, prepare the pocket itself. Fold the top edge down and sew it to create a clean hem. Then, fold and press the other three sides of the pocket. Use your pattern to find the right spot for the pockets on the front of your shacket. Pin them in place and topstitch them on. Finally, add the pocket flaps just above the pockets.
Step 6: The Finishing Touches

You are so close to the finish line! The last few steps will make your DIY oversized shirt jacket complete.
First, hem the bottom of the shacket. Simply fold the bottom edge up twice and sew it in place for a clean finish.
Next, it’s time for buttonholes and buttons. Your sewing machine probably has a special setting for making buttonholes. Practice on a scrap piece of fabric first to get the hang of it. Mark where you want your buttonholes to go down the front placket and on the cuffs. Once you’ve made the buttonholes, use a seam ripper to carefully open them up.
Finally, sew your buttons on. A good trick is to lay the placket with the buttonholes over the other placket and use a pin to mark where each button should go. Sew them on securely, and you’re done!
