DIY Racerback Workout Shirt Tutorial

You can print the above and place it next to you while you cut!


– Old t-shirt (I used my old college tshirt! We were Home of the Fighting Poets. Hahahahaha. How threatening :P)

– Pair of scissors

TIME: 15 min


1. Cut away the crew neck the sleeves and the bottom. For the sleeves, you will want to start at the shoulder (you decide how thick you want the strap to be) and cut straight into the chest area. Then curve. If you curve the whole way, it’s gonna look weird on you. If you have no idea what I am talking about, no worries, just follow the tutorial, you can always snip away later. Tr to follow my pictures.

2. Clean up the edges. Decide how low you want the neckline to be.

3. Turn the shirt to the back and make a narrower racerback.  Then cut a deep V.

4. Take the bottom edge of the shirt that you cut off and cut the seams off so that you’re just left with fabric.

5. Stretch it like a maniac. This is fun.

6. You’re left with a really cool noodle thing. It’s really long too!

7. About 2″ above the bottom of the V tie a know with one edge of the noodle.

8. Wind it round ‘n round, then double knot it at the other end too. Cut off loose ends.

9. To make this a hi-low top, lay your shirt sideways and flat. Then starting at about 4-5″ from the front center of the shirt start diagonally cutting down til you reach the back. You’ll want to cut straight for a bit at the front center then start creating the diagonal or else you’re gonna get a weird arrow shape with you open up.

DONE! Start pulling at the fabric to make rough edges go curly and to make your tank longer.

What a fab way to reuse old shirts as vintage gym fashion! I love it. When you guys make yours, please share it on facebook or tweet it to me @Blogilates.

Wear with a bright bra to make it pop!

Oh and be sure to be the first to pin this to Pinterest! GO!

  • Becca

    I love this! I have a ton of old t shirts lying around that I never wear anymore, but soon I will be wearing them again, just as tank tops! I also have a few very oversized t shorts, I wonder if this will work on them too? I don’t know, but I will try!

  • Denise

    Just made this – so easy!! I love it. Workouts are going to be so much more comfortable now. My only suggestion to people considering this is: use a shirt that is slightly baggy on you and a bit long. Once you start cutting and tying the back, and cut off the bottom (I only cut about an inch – half an inch was the seam and half an inch of fabric to weave up the back) it might be a bit short. I’m only 5’3″ so length isn’t a problem, but if I were taller I’d have to use a larger shirt for the length. Thanks for posting this!!

  • jackie and steph

    we just did this….aaaand it looks awesome. thanks!!!
