Turn old clothes into new looks and give yourself more cute outfit options to choose from. Utilize these cutting tips and techniques to accomplish a cute DIY workout tank top from t-shirt. 

  • Cutting Tips: When working with very fine lightweight jersey knit, be careful to only pick up the back layer of the tee. You don’t want to accidentally cut through the front layer of the shirt at the same time. 
  • Fabric Glue: Always test the fabric glue on a scrap piece to make sure it works before beginning the full application. Smooth the surface and let the glue completely dry overnight before trying it on the clothes. Test the strength of the bond and make sure that you are using a permanent fabric glue rather than temporary.
  • Save the Remnant: It’s always good habit to save leftover pieces of fabric to use for another project. From sleeves, to neckbands or even hemming, scrap fabric is always useful to have around.
  • Hemming: Since this tutorial is a no-sew project, i would like to share some clothing making basics. When you cut the t-shirt, you will see the cutline keep curling. Don’t worry! The knit fabric won’t fray, so you can leave it as it is!
  • Measuring Tape: Make use of a tape measure when working on a garment. The flexible tape is quite different than a plastic ruler, it can easily measure curved lines in longer distances.

I made this tank top with back overlap because it will holds the gap open a little bit, and not completely open when in motion. This is so cute to wear for a workout, after yoga or even while going for a hike.

Follow along with this simple step-by-step upcycle tutorial to make your t-shirt into a back slit tank top. You'll be amazed how easy the project really is.



  • Fabric Chalk
  • Measuring Tape
  • Ruler
  • Scissors


  1. First of all, measure 1” down under the sleeve and mark with chalk. In addition, measure ½” along the shoulder seam and again mark with chalk
    Measure from the shoulder hem towards the neck opening to determine where to cut the sleeveless tank top.
  2. Next, draw the new armhole with fabric chalk.
    measure from the under arm down the sides for the other mark of the sleeveless tank top.
    Pro tip: I recommend drawing a smooth curve following the sleeve line.
    Draw with fabric chalk to mark the cut line for the sleeveless tank top arm openings
  3. Then, cut along the chalk line to make the new arm holes.
    Cut along the line to remove the sleeves and create a tank top.
  4. Now, lay the sleeveless shirt flat and fold the shirt in half.
    Now the t-shirt is a tank top
  5. When cutting make sure you only cut through the back piece and not the front piece.
    Cut along the center line of the back piece.
  6. From the back center neckline, measure 1” across and glue. Then, overlap with the back piece and secure it in place.
    Measure the neck opening to overlap the neck piece and secure with fabric glue.
  7. When the glue is completely dried, try on your DIY no sew t-shirt refashion and tie a bow in the back.
    Tie a knot with the shirt piece at the bottom of the back slit.


I recommend using an oversized t-shirt with a wide neckline that has modal ingredients. The fabric will feel lightweight and also keep you airy during a hard workout. 

This upcycle is an easy no sew t-shirt to tank top that keeps your workout gear looking stylish. Experiment with the fun ways to cut a shirt.

Great designs! My hubby has a bunch of gym shirts that are made from that quick dry material, kinda smooth and shiny, could I still use those or would the material not cut the same as cotton? Thanks!

Thank you so much! Knit fabrics won't fray, so you should be able to cut the quick dry t-shirt into a back slit tank top.
