Why Make Your T-Shirt Fit Better?
Making changes to your t-shirts is worth the effort. It can turn a basic shirt into something special just for you.
- Better Look: A shirt that fits well just looks better. It shapes to your body instead of looking baggy or tight.
- More Comfort: Clothes that fit right feel better to wear all day. No more pulling or tugging.
- Save Money: You can update shirts you already own instead of buying new ones. You can rescue shirts you thought you couldn’t wear anymore.
- Show Your Style: You can make a shirt truly yours. Change the shape to match your personal style, maybe making it a slim fit t-shirt.
It’s a fun way to be creative and wear clothes that feel made for you. This DIY t-shirt alteration lets you take charge of your closet.
Getting Ready: What You Need
Before you start tailoring your t-shirt, get all your tools ready. Having everything close by makes the job much easier.
- The T-Shirt: Choose the shirt you want to make changes to.
- A Shirt That Fits Well: Find a shirt you love the fit of. You will use this as a guide.
- Fabric Scissors: Sharp scissors are a must for cutting fabric cleanly.
- Pins: You need pins to hold fabric in place before you sew.
- Measuring Tape: Use this to check lengths and widths.
- Seam Ripper: This small tool helps you take out stitches if you make a mistake. Everyone makes mistakes!
- Tailor’s Chalk or Fabric Pen: These make marks on the fabric that you can wash away later.
- Matching Thread: Pick a thread color that is close to your t-shirt color.
- Sewing Machine: This makes sewing fast and strong. Most t-shirts are made of knit fabric, which stretches. A sewing machine with a stretch stitch or a serger works best for knit fabrics.
- Needle and Thread: You can use a needle and thread for small parts or if you don’t have a sewing machine. It takes longer but is good for small fixes. Use a ballpoint needle for knit fabrics, whether you sew by hand or machine. It slides between the fabric loops instead of piercing them.
Having these items ready helps you move smoothly through the steps. Getting ready is the first big step in your resizing t-shirt project.
Finding the Fit: Where to Make Changes
Put on the t-shirt you want to alter. Stand in front of a mirror. Look closely at how the shirt fits you. Compare it to the shirt you like. Where is it too loose? Where is it too long?
Common places to alter a t-shirt are:
- The Sides: The body of the shirt might be too wide, making it look boxy. Taking in sides t-shirt is a popular change.
- The Sleeves: Sleeves might be too long or too wide. You might want to shorten t-shirt sleeves or make them narrower.
- The Length: The shirt might be too long overall.
- The Shoulders: Sometimes shoulders are too wide, but this is a harder fix for beginners.
- The Neckline: This is also a trickier change, often best left until you have more practice.
Focus on the easy parts first: sides, sleeves, and length. These give you the biggest change in how the shirt looks and feels with the least trouble. Making these changes helps you reduce t-shirt size effectively.
Making the Body Smaller
This is often the most common change people want. If your t-shirt is too wide in the chest, waist, or hips, taking in the sides can give you a much better shape.
Pinning the Sides for a New Fit
First, turn the t-shirt inside out. Lay it flat on a table. Lay your well-fitting shirt directly on top of the one you want to alter. Line up the shoulder seams and necklines.
Now, look at the sides of the shirt that fits well. See how its side seams curve? Use tailor’s chalk or a fabric pen to draw a line on the too-big shirt. Draw this line following the side seam of the shirt that fits. Start near the armpit and draw down to the bottom hem.
Make sure you leave some extra space outside your drawn line. This extra space, about half an inch to an inch (1-2.5 cm), is called a seam allowance. You need this space to sew without the fabric edge coming undone.
Use pins to hold the two layers of the too-big t-shirt together along your drawn line. Do this on both sides of the shirt. Pin carefully, making sure you are pinning both the front and back of the shirt evenly.
If you don’t have a shirt that fits well, you can put the too-big shirt on inside out. Pinch the extra fabric along the sides until the shirt feels right. Pin the pinched fabric carefully, making sure the pins go straight in so you can take the shirt off easily. Take the shirt off and lay it flat. You will see the pins mark a line. Draw a chalk line next to the pins, giving yourself that seam allowance.
Make sure the curves look smooth. The line should curve in gently at the waist and maybe flare out slightly at the hip, just like your body. Drawing the line is key to getting the fit right.
Sewing the New Side Seams
Take your pinned t-shirt to your sewing machine. Choose the right needle for knit fabric (a ballpoint or stretch needle). Set your machine to a stretch stitch. If your machine doesn’t have a stretch stitch, use a small zig-zag stitch. A regular straight stitch will break when the fabric stretches.
Start sewing from the armpit area down to the bottom hem. Sew carefully along the chalk line you drew. Backstitch at the start and end of your seam. This means sewing a few stitches forward, then a few backward, then forward again. This locks the stitches so they don’t unravel.
Sew slowly, guiding the fabric with your hands. Don’t pull or push the fabric hard. Let the machine feed it through. Sew both sides following your chalk lines.
After you sew, try the shirt on carefully (before cutting anything!). Check the fit. Does it feel right? Is it still too loose or too tight? If it’s too loose, you can draw a new line closer to the body and sew again. If it’s too tight, use your seam ripper to carefully take out the stitches and sew a new line farther away from the body. It’s always better to take in too little at first than too much. You can always sew it smaller, but you can’t add fabric back easily.
Trimming and Finishing the Edges
Once you are happy with the fit, take the shirt off and turn it inside out again. You will see your new seam and the original side seam, with extra fabric outside your new seam.
Use your fabric scissors to cut away the extra fabric. Cut about half an inch (1 cm) away from your new stitched line. Don’t cut too close!
Knit fabric, like t-shirt fabric, doesn’t fray much. But the cut edge can still roll or look messy. To finish the edge, you have a few choices:
- Serger: If you have a serger, this is the best way to finish knit seams. A serger cuts the edge and wraps it in thread all at once. This creates a clean, stretchy finish.
- Zig-zag stitch: On your regular sewing machine, use a medium width and length zig-zag stitch. Sew along the raw edge of the fabric you just cut. This stops the edge from rolling.
- Overlock stitch: Some sewing machines have a stitch that looks like a serged edge. Check your machine’s manual for an “overlock” or “edge finishing” stitch.
- Pinked edges: You could use pinking shears (scissors with zig-zag blades) to cut the edge. This is the simplest finish but doesn’t stop the edge from rolling completely.
After finishing the edges, press the new seams flat with an iron (use a low setting if the fabric is sensitive). Pressing makes your sewing look much more professional.
By taking in sides t-shirt, you have successfully resized t-shirt body! You’ve started your DIY t-shirt alteration journey.
Making the Sleeves Fit Better
Sometimes the body fits, but the sleeves are too baggy or too long. You can shorten t-shirt sleeves or make them narrower.
Deciding on Sleeve Length and Width
Put the shirt on again. Decide how long you want the sleeves to be. Mark the desired length with a pin or chalk. Take the shirt off. Measure from the original sleeve hem up to your mark. Add about an inch (2.5 cm) to this measurement for the new hem allowance. This is where you will cut.
If the sleeves are too wide, you can take them in along the underarm seam. Pin the extra fabric from the underarm down to the sleeve hem, similar to how you pinned the sides of the shirt body. Remember to follow the curve of the original seam.
Shortening the Sleeves
Turn the shirt inside out. Lay the sleeve flat. Measure up from the original hem the amount you decided, plus the hem allowance. Draw a chalk line across the sleeve at this point.
Cut along the chalk line using your fabric scissors. You now have a shorter sleeve.
To create a new hem, fold up the raw edge by about half an inch (1.25 cm) towards the inside of the sleeve. Press this fold. Then fold it up again another half an inch (1.25 cm). This hides the raw edge. Pin the double fold in place all the way around the sleeve opening.
Take the sleeve to your sewing machine. Use a stretch stitch or a small zig-zag stitch. Sew close to the inside folded edge, all the way around the sleeve opening. Make sure you catch the folded edge underneath as you sew. Backstitch where you start and end.
If you want a look more like a store-bought t-shirt hem, some machines have a double needle setting. Using a double needle creates two parallel lines of stitching on the outside and a zig-zag stitch on the inside that stretches. If you have a double needle and your machine can use it, thread it and sew the hem allowance with it.
If sewing by hand with a needle and thread, use a small hemming stitch or a catch stitch that allows for some stretch.
Repeat on the other sleeve. You have now successfully learned how to shorten t-shirt sleeves.
Making Sleeves Slimmer
If you pinned the sleeves to make them narrower, draw your chalk line following the pins, adding a seam allowance.
Turn the shirt inside out. Lay the sleeve flat. Pin along your chalk line through both layers of the sleeve.
Sew along your chalk line from the underarm seam down to the new sleeve hem (or original hem if you didn’t shorten them). Use a stretch stitch or small zig-zag stitch on your sewing machine. Backstitch at both ends.
Try the shirt on to check the fit. If it’s good, trim the extra fabric about half an inch (1 cm) from your new seam. Finish the raw edge with a zig-zag stitch or serger, just like you did for the body seams. Press the seam flat.
Making these changes helps the sleeves fit your arms better and improves the overall fit t-shirt look.
Making the Bottom Shorter
Is your t-shirt just too long? Making the bottom shorter is a straightforward change.
Measuring and Marking the New Hem
Put the shirt on. Decide how much shorter you want it. Mark the desired length with a pin or chalk. Take the shirt off.
Measure from the original bottom hem up to your mark. Let’s say you want to cut off 3 inches. You need to cut 3 inches plus the amount you will use for your new hem. A typical t-shirt hem uses about 1 inch (2.5 cm) of fabric folded twice (half an inch + half an inch). So, you would cut 3 inches + 1 inch = 4 inches off the bottom.
Turn the shirt inside out. Lay it flat. Measure up from the original hem the total amount you need to cut off (e.g., 4 inches). Draw a straight chalk line all the way across the shirt at this point. Make sure your line is even from side to side.
Cut along your chalk line with fabric scissors. Your t-shirt is now shorter!
Sewing the New Hem
Now you need to create the new bottom hem. This works just like hemming the sleeves.
Fold up the raw bottom edge towards the inside of the shirt by about half an inch (1.25 cm). Press this fold with an iron.
Fold it up again by another half an inch (1.25 cm). This hides the raw edge inside the double fold. Press this second fold. Pin the double fold in place all the way around the bottom opening of the shirt.
Take the shirt to your sewing machine. Use a stretch stitch or a small zig-zag stitch. Sew close to the inside folded edge, all the way around the hem. Backstitch at the start and end. Again, you can use a double needle here if you have one for a professional look.
If sewing with a needle and thread, use a stretchy hand stitch like a catch stitch or a flexible hemming stitch.
Press the finished hem flat. Your shirt length is now perfect for you!
Other Simple Adjustments
While sides, sleeves, and length are the most common, you might consider other easy changes after you’ve practiced.
- Straightening the sides: If the original side seams are twisted (common in some cheap t-shirts), you can follow the steps for taking in sides t-shirt but just sew a new straight line from armpit to hem, ignoring the old twisted seam. This won’t make the shirt smaller, but it will look neater.
- Reshaping the bottom: Instead of a straight hem, you could curve the bottom hem up at the sides for a different look. This requires a bit more careful cutting and sewing the curved hem.
Remember, the goal is a fit t-shirt that makes you feel great wearing it. Keep your DIY t-shirt alteration simple at first.
Tips for a Pro Look
Want your tailored t-shirt to look like it came from a store, not homemade? Follow these tips.
- Pressing is Key: Ironing your fabric before cutting and pressing your seams after sewing makes a huge difference. Pressing makes stitches sink into the fabric and makes edges crisp. Use the right heat setting for your fabric.
- Use the Right Needle and Thread: For stretchy t-shirt fabric (knits), always use a ballpoint or stretch needle. A regular sharp needle can break the fibers and cause small holes or runs. Use polyester thread, as it has some stretch and is strong.
- Practice First: If you are new to sewing or sewing on knits, practice on an old t-shirt you don’t care about. This helps you get the feel of the fabric and your sewing machine settings.
- Go Slow: Sewing slowly gives you more control and results in straighter, neater seams.
- Measure Twice, Cut Once: Double-check your measurements and chalk lines before you cut! It’s hard to add fabric back.
- Basting: If you are nervous about sewing the final seam, sew a test line with a long stitch length first (this is called basting). Try the shirt on. If the fit is perfect, sew over the basting stitch with your final stitch length. Then you can remove the basting stitches.
Following these tips will help you achieve a professional finish on your resizing t-shirt project.
Common Mistakes and How to Avoid Them
Even experienced sewers make mistakes. Here are some common ones when tailoring t-shirts and how to steer clear.
- Sewing with a Straight Stitch on Knits: This is a big one. Knit fabric stretches. If you sew with a straight stitch, the first time the seam stretches (like when you put the shirt on), the stitches will pop. Always use a stretch stitch, zig-zag, or serger.
- How to avoid: Know your sewing machine. Test stitches on a scrap of the t-shirt fabric first. Find the stretch stitch or the right zig-zag setting before you start sewing the shirt.
- Cutting Too Much Fabric: It’s easy to get carried away when taking in sides t-shirt or shortening the hem.
- How to avoid: Measure carefully. Draw your chalk line with seam allowance. Pin thoroughly. Try the shirt on before you cut any excess fabric. Remember you can always take more off, but you can’t easily add it back.
- Wavy Seams and Hems: Knit fabric can get stretched out of shape while you are sewing it, leading to wavy edges.
- How to avoid: Don’t pull the fabric while sewing. Let the sewing machine’s feed dogs do the work. Use a walking foot on your sewing machine if you have one – it helps feed both layers of fabric evenly. Pressing your seams afterward can also help flatten slight waves.
- Skipped Stitches: Sometimes the sewing machine skips stitches on knit fabric. This can happen if the needle is wrong, dull, or the thread tension isn’t right.
- How to avoid: Make sure you are using a brand new ballpoint or stretch needle. Change your needle often (every 8-10 hours of sewing). Check your machine’s tension settings. Sometimes sewing on a thin strip of tissue paper or stabilizer under the fabric helps prevent skipped stitches; you can tear it away afterward.
- Uneven Sides or Sleeves: One side or sleeve ends up shorter or wider than the other.
- How to avoid: Fold the shirt in half lengthwise after pinning or drawing your lines. Check that the lines or pins on both sides match up. When hemming sleeves or the bottom, measure carefully from the original edge to ensure your new cutting line is even all the way around.
Being aware of these potential problems will help you tackle your DIY t-shirt alteration project with more success.
Caring for Your Newly Tailored Shirt
Once you’ve put in the work to alter your t-shirt and get that perfect fit, you want it to last.
- Washing: Wash your tailored t-shirt as you normally would. The seams you’ve sewn with a stretch stitch or zig-zag should hold up well in the washing machine. Using cold water can help keep the fabric from shrinking or stretching too much.
- Drying: To help keep the shape and fit you created, it’s best to air dry your tailored t-shirt by laying it flat or hanging it. If you use a dryer, use a low heat setting. High heat can cause knit fabrics to shrink or lose their shape.
Proper care will help your slim fit t-shirt or resized t-shirt stay looking good for a long time.
Table: Common T-Shirt Alterations
Here is a quick look at common changes you can make:
| Alteration | What it Fixes | Skill Level | Tools Needed | Fabric Type Note |
|---|---|---|---|---|
| Taking in Sides | Shirt body too wide, boxy fit | Beginner/Easy | Pins, chalk, measuring tape, sewing machine (or needle/thread), scissors, iron | Use stretch stitch/zig-zag for knit fabrics |
| Shortening Length | Shirt body too long | Beginner/Easy | Pins, chalk, measuring tape, sewing machine (or needle/thread), scissors, iron | Use stretch stitch/zig-zag for knit hem |
| Shortening Sleeves | Sleeves too long | Beginner/Easy | Pins, chalk, measuring tape, sewing machine (or needle/thread), scissors, iron | Use stretch stitch/zig-zag for knit hem |
| Slimming Sleeves | Sleeves too wide | Beginner/Easy | Pins, chalk, measuring tape, sewing machine (or needle/thread), scissors, iron | Use stretch stitch/zig-zag for knit seams |
| Adjusting Shoulders | Shoulders too wide, shirt doesn’t sit right | Intermediate | Pins, chalk, seam ripper, sewing machine, scissors, iron | Can be tricky with neckband, often involves seam ripper |
| Reshaping Neckline | Neck too high/tight or too wide/low | Intermediate | Pins, chalk, seam ripper, sewing machine, scissors, iron, ribbing fabric (maybe) | Tricky, involves changing the neckband and stretch |
As you can see, taking in sides t-shirt, shortening length, and shortening sleeves are great starting points for your alter t-shirt projects.
Comprehending Knit Fabric
T-shirts are usually made from knit fabric, like jersey. Knit fabric is different from woven fabric (like denim or bed sheets).
- How it’s Made: Knit fabric is made by looping threads together, like knitting. This makes it stretchy.
- Why Stitch Choice Matters: Because it stretches, you need stitches that can stretch with it. A straight stitch won’t stretch and will break. A zig-zag or stretch stitch moves with the fabric.
- Why Needles Matter: A sharp needle can cut the loops in knit fabric, causing runs. A ballpoint or stretch needle has a rounded tip that pushes between the loops instead.
Being aware of these things helps you choose the right tools and methods for your DIY t-shirt alteration.
Frequently Asked Questions
- Q: Is it hard to tailor a t-shirt?
A: For basic changes like taking in the sides, shortening sleeves, or shortening the bottom, it’s actually quite easy for a beginner. It gets harder for things like shoulders or necklines. Start with the simple stuff! - Q: Do I need a sewing machine?
A: A sewing machine makes the job faster and stronger, especially for seams and hems. But you can use a needle and thread for small changes or if you are very patient. You’ll need to learn stretchy hand stitches. - Q: What kind of thread should I use?
A: Use polyester thread. It’s strong and has a little bit of stretch, which is good for knit fabrics. - Q: My sewing machine is making wavy seams on my t-shirt. What’s wrong?
A: You might be pulling the fabric as you sew, or the machine’s presser foot might be stretching the fabric. Try not to pull, let the machine feed the fabric. A walking foot attachment can help. Also, check your needle; make sure it’s a ballpoint or stretch needle and is new. - Q: Can I make a t-shirt two sizes smaller?
A: Yes, you can significantly reduce t-shirt size. Taking in the sides quite a bit and maybe slimming the sleeves can make a big difference. However, changing the shoulder fit is harder and might be necessary if the shirt is much too big. Start with the sides and see if that gives you the fit you want.
These are common questions when you start to alter t-shirt clothes yourself.
