In this tutorial, I’m going to show you how to make an upcycled split t-shirt.

If you have a basic, regular t-shirt and you’re looking to make it more interesting and contrasting, this DIY is for you. Let's get started.

Tools and materials:

  • Sewing machine
  • 2 t-shirts
  • Scissors
  • Iron
  • Clips

1. Choose your two t-shirts

The first thing you need to do is make sure that the t-shirts you're using are the same size.

If they're not the same size, it's going to be a little bit crooked, though that might be a look you like.

If you want it to look seamless, get them the same size. If you want the top to look a bit asymmetrical, then you can go for two t-shirts that aren’t the same size.


Ironing one t-shirt

2. Iron one t-shirt

Take the first t-shirt, fold it in half lengthways and iron it down flat for a clean look.


Where to cut

3. Cut the t-shirt in half

Now you will have a crease in the middle and that's the crease that you're going to follow to cut. 

Proceed to cut the t-shirt in half.

Repeating steps

4. Repeat

Repeat steps 2 and 3 with your second t-shirt.


Pinning t-shirt

5. Pin the back sides

Place the two halves of the t-shirt next to each other so they look like one complete t-shirt.

Then, open up the front of the t-shirt so the back side is facing you.

Pinch the two pieces with the right sides together and pin them all the way along the seam.

I'm going to use a seam allowance of 0.5 inches. The seam allowance is up to you, it all depends on how you want the shirt to fit.


Sewing t-shirt

6. Sew the back sides

Once you’ve finished clipping it, sew the t-shirt together leaving the seam allowance.


Ironing seams

7. Iron the seams

When done, take an iron and press the seams open.

The fabric of my t-shirt doesn’t fray so I’m going to keep the raw edges as they are. But, if the fabric that you’re using is one that frays, I recommend topstitching the seams so that they won't unravel.

8. Pin and sew the front sides

Proceed to clip the front two sides together and sew them. Then press the sides open with an iron.

This DIY split t-shirt literally looks like I bought it like this! It has a nice clean finish, and it looks so professional.

If you're a newbie to slow fashion and you're just getting into making your own clothes, this is a perfect DIY for you as it is very straightforward.

Not only that, but it will also motivate you to create more and to continue sewing. I love upcycling my clothes as it allows me to live a sustainable lifestyle and I hope you’ll give this project a go.
