Necessary Materials

Before you start altering your blazer, make sure you have the following materials on hand:

  • Scissors

  • Measuring Tape or Ruler
  • Chalk or Fabric Marker

11 Step-by-step Guidelines on How to Alter a Blazer Without Sewing

Step 1: Measure and Mark

The first step to altering your blazer without sewing is to measure and mark where you want to make the necessary alterations. Use a measuring tape or ruler to make precise measurements, and then mark the areas with chalk or a fabric marker.

Use a Measuring Tape

You can mark areas such as the sleeves, length, and waistline. It’s best to try on the blazer and make adjustments while wearing it, so you can see how the alterations will look in real time.

Step 2: Cut Along the Marks

Once you have marked all the necessary areas, use your scissors to cut along those marks. For example, if you want to shorten the sleeves of your blazer, cut them at the desired length. Make sure to cut along the seam lines for a clean finish. It’s always better to cut off less at first, as you can always go back and make further adjustments if needed. But once you’ve cut too much, there’s no going back.

Step 3: Hem the Cut Edges

After cutting along the marks, you may notice some frayed edges. To prevent this, use fabric glue or iron-on hem tape to seal off those raw edges. This will give your blazer a more professional and polished look without having to sew. It’s important to follow the instructions on the product you’re using and let it dry completely before moving on to the next step.

Step 4: Altering the Waistline

To alter the waistline of your blazer, first, try it on and determine how much you want to take in. Use pins or fabric clips to secure where you want to take in the waistline. Then, remove the blazer and glue or iron along the pins to secure the excess fabric in place. Let it dry completely before removing the clips and trying on your altered blazer. You may need to repeat this step a few times until you achieve the desired fit.

Use Pins or Fabric Clips

Step 5: Adding Darts

If you want a more fitted look, you can add darts at the back of your blazer. To do this, turn the blazer inside out and mark where you want to add the darts with chalk or fabric marker. Then, fold the fabric along that line and glue or iron in place. This will give your blazer a more structured look without having to sew.

But if you do know how to sew, you can also stitch the darts in place for a more permanent solution. This method works best for blazers that are made of non-stretchy fabrics.

Step 6: Adjusting the Length

To alter the length of your blazer, try it on and determine where you want it to hit. Use pins or fabric clips to mark that length, then take off the blazer and cut along those marks. Use fabric glue or iron-on hem tape to seal the cut edges and let it dry completely before wearing.

It’s always better to cut off less at first, as you can always go back and make further adjustments if needed. Heed caution when cutting your blazer, as you don’t want to end up with an unintentional crop top.

Step 7: Adding Patches

Patches are a great way to add some personality and interest to your blazer. You can either use pre-made patches or create your own by using fabric and iron-on adhesive. Simply cut the fabric into desired shapes and glue or iron them on. You can also add patches to cover up any imperfections or holes on your blazer.

But be careful not to overdo it – less is more in this case. It’s best to stick with one or two statement patches.

Step 8: Experiment with Collars

If you have a blazer with a traditional collar, you can easily change its style by experimenting with different collars. For example, you can add a detachable fur or faux-fur collar for a cozy and chic winter look. Or, you can use a fabric scarf to create a unique and eye-catching necktie collar. The possibilities are endless, so have fun with it!

Step 9: Accessorize with Brooches or Pins

Another easy way to alter the look of your blazer is by accessorizing it with brooches or pins. You can add them to the lapel or pockets of your blazer to give it a touch of personality and style. Plus, you can easily remove them if you want to switch up the look again.

It’s a quick and effortless way to elevate your blazer game. You can even use vintage brooches for a touch of nostalgia. It’s all about personalizing your blazer to make it unique and one-of-a-kind.

Step 10: Add Embellishments

Similar to adding patches, you can also add embellishments like rhinestones, studs, or beads to give your blazer a unique and personalized touch. You can use fabric glue or iron-on adhesive to attach the embellishments to any design you desire. Just make sure to let it dry completely before wearing it.

This is also a fun way to breathe new life into an old blazer. You can turn a plain and simple blazer into a statement piece with just a few added embellishments.

Step 11: Final Touches

Once you’ve completed all the necessary alterations, try on your blazer and make any final adjustments needed. You can also use a steamer or iron to smooth out any wrinkles or creases that may have occurred during the alteration process. Now, you have a fresh and updated blazer without sewing a single stitch!
