How to Sew a Women’s High-Low Racerback Tunic
Here’s what you need to make your own racerback high-low tunic just in time for summer!
SUPPLIES:
- 2-2 1/2 yards knit fabric (you’ll want something with some stretch to it)
- 1/2 inch wide elastic
- Shirt to use as a template
- Disappearing ink marker
- Rotary cutter and mat
- Measuring tape
- Iron and ironing board
- Sewing machine
- Basic sewing supplies
Drafting and Cutting Out Your Pattern and Pieces:
TWO: after I had my front bodice pattern, I modified the pattern piece to make the back bodice racerback-style, as shown in the picture above. You could also trace an existing racerback shirt for this.
THREE: to draft the bottom of my tunic, I simply matched up the edge of my front bodice piece with a piece of paper and taped it down. Then I drew an A-line from the armpit down until it reached the length I wanted (about 37 1/2 inches from shoulder to the bottom of the tunic.)
FOUR: with your fabric folded right sides together (RST) and the stretch going horizontally, place your pattern on the fold and cut with a rotary cutter to create the front of your tunic (make sure you don’t cut the fold!).
FIVE: for the back, simply switch out the front bodice pattern with your back bodice pattern and tape to secure. Place pattern on fold and cut as you did for the front.
SIX: you should now have a front piece and back piece cut out.
Making Bias Tape:
Before we move on to the assembly, I want to give a quick lesson on how to make your own bias tape, which you’ll use to conceal the raw edges of your fabric. You could always fold over and sew the raw edges of your fabric, but I like the finished look of using bias tape.
ONE: (see steps below that explain how to get the measurements for your bias tape.) Once you have your measurements, cut out strips of fabric on the bias (learn more about that here) 2 inches wide. You should have 3 strips of fabric: one for your neckline, and one piece for each of your arm holes.
TWO: either fold each side of your strips over to meet in the middle and iron or, if you have a bias tape maker like I do (and if not, go get one at your local hobby store!), run it through your bias tape maker and iron.
THREE: finally, fold the strip in half long ways and iron. Done!
Assembly:
THREE: use your tape measure to measure the length of your neckline from shoulder to shoulder, then use the instructions on how to make bias tape above to make bias tape for your neckline. Encase the raw edges of your neckline in the bias tape you just made. Pin all along the top neckline and topstitch, being sure to catch the other side of your bias tape as you sew.
FOUR: fold your tunic with the front and back facing again and match up the other shoulder of your tunic. Sew to join the other shoulder as you did above. Open your tunic back up, then measure each arm hole and cut bias tape for each. Encase the raw edges of each armhole in bias tape. Pin and sew.
FIVE: with the front and back pieces RST, match up the sides of your tunic and pin from the armholes down. Sew the sides to join and turn right side out.
Making Your Tunic High-Low:
ONE: rotate your side seams so that they are matched up in the middle of your tunic. The front of your tunic will be facing left, and the back of your tunic will be facing the right (see picture above.) Place the tunic on your rotary mat and cut from front to back in a kind of “s” shape as shown along the white guideline in the picture above.
TWO: when you unfold your tunic, it should have the high-low effect. If you need to make any adjustments to the high-low hemline, match up the side seams in the middle again and cut again until you’re happy with the outcome. Hem the bottom or leave raw, up to you!
Cinch The Waistline:
You could just stop here if you like your tunic, but I wanted to add some elastic at the waist to make it more flattering. ONE: try the tunic on and mark right above where your bellybutton is (mine was about 16 inches down from the shoulder.) Turn the tunic inside out, and use your disappearing ink marker to draw a straight line on both the front and back of your tunic to act as a guideline for your elastic.
TWO: measure your waist and subtract an inch, then cut this amount of elastic out (I have a 30-inch waist, so I cut my elastic to be 29 inches long.) Use a zig-zag stitch to join the edges together.
THREE: with your tunic inside out, pin your elastic to either side of your tunic along the guideline you drew.
FOUR: start at one side of your tunic and use a zig-zag stitch to secure the elastic to your tunic along the line you drew, stretching the elastic as you go. Hold the back of the elastic with one hand and pull the other side of the elastic with your other hand as you sew. Turn inside out, and done!
Throw on a pair of leggings and wear your new tunic proudly! In an ideal situation, I would have lined up the front and back to make the pattern continuous, but since I was barely working with 1 1/2 yards, I made do. With such a busy pattern, you don’t really notice. At least that’s what I tell myself 🙂
Thanks so much for stopping by, and until next time…
Happy Sewing!

I LOVE this Jen! So funny it totally looks like a lovely silk in the photos.
Thanks, Mie! It was a good find. You better believe I’ll be digging in the depths of the fabric department more often 🙂
Thank for offering such a great pattern. Now, I have something to do with may fabric with the weird pattern, that I couldn’t not buy.
The right pattern is all you need sometimes!
LOVE it!
Thank you!
Nice! I’ve been looking for something to make that would be more flattering for my postpartum body. This looks like it will fit the bill.
This would definitely be very flattering! And congrats on the little one!
Great tutorial! The fabric is totally perfect for this pattern!
Thanks, it was a great find (even if I didn’t think so right away!)
Wal Mart?? Say Whaaaat?? That’s totally cute!
I’m getting a lot of wear out of it already!
Super cute! Can’t wait to try this out
I’d love to see pictures if you make one!
I love this look! I am going to have to make some for me and for my girls thanks so much for sharing this.
Thanks Felicia! Let me know if you have any questions 🙂
I like this so much! Thanks for sharing the pattern. I’ll try to make one as soon as I can!
I can’t wait to see what you come up with!
Jen – I love this top! Great tutorial!
Thank you Elisa!
Looks great!I wanted to hack a too large t-shirt into something like this. You’ve given me a bit more courage 🙂
Refashioning old shirts is my favorite. I have a whole box of old clothes waiting to be hacked up!
Oh I love this top! Great to wear with leggings which is always challenging I find. Now if only I would work up the courage to sew for me!
Sewing for yourself is so rewarding, don’t be nervous! I used to only sew for my kids, but I’m so glad I have a few handmade pieces for myself that I can be proud of.
So, this was a really cool and interesting method to create a simple and fun top. Great job!
Thanks! This was a project I just couldn’t get out of my head. I’ll be making many more I’m sure 🙂
Brilliant tutorial, thank you. Definitely trying this. Love the fabric too, I have a thing for ugly/pretty prints.
It’s funny how the quirky prints can be transformed with the right pattern!
