Whenever I make a cute top, I can’t help but think about how I could make it into a cute workout top! The Stitch Upon A Time Titania Top & Tunic was the perfect base for a workout top hack. Since dresses are a year round staple for me, it’s also going to end up as a dress once I add 8 or 9 inches to the tunic length. The tunic itself turned out quite cute. I like the flowy body, especially in this silky soft circular knit. It has the perfect drape for this pattern. Can you imagine the twirl in a dress length?


Can you see my elastic error in these photos? Instead of following the elastic length cut chart for the armscye, I thought the elastic should be more taught. Making it 2 inches shorter than recommended gave me puckering and a bit of rolling at the armpits. I should know by now to trust Jennifer of Stitch Upon A Time’s design and testing and use the recommended length! The neckband was easy to sew, and despite being a higher neckline than I normally wear, the rounded shape doesn’t cut into my neck or shoulders. Using the built in shelf bra means not having to worry about wearing a strapless bra, or trying to find a bra with straps that don’t show. The stylish tunic would look great with skinny jeans or fitted pants like the Goldilegs Jeans, and of course with a slim skirt or shorts.
Hacking the shelf bra pieces into a workout top is easier than you think. Cut two bra fronts out of Supplex. Rather than cutting the back out on the fold of the fabric, I folded my pattern piece under 5/8″ from the center back, and cut out two left back and two right back pieces. You’ll also cut a bra front and a right and left back out of powernet or techsheen for support. For design purposes, I wanted the bra back to have a 2″ strip of powernet down the center, with a little opening between the bra top and the tank body. I used my favorite tank pattern to make the bodice. If you don’t have a tank pattern, trace any well fitting tank in your closet. Don’t forget to add seam allowances!
The trickiest part of this workout top is the V-cutout on the center front. Lay your clear ruler on an angle, starting 1″ from center front at the top, and down 5-1/2″. Do the same thing to the second bra front piece, then trim the 3/8″ seam allowance off the second triangle cutout opening. The trimmed version will become your front lining piece.


Lay the triangle you cut out of the bra front on your powernet. Add 3/4″ width to each of the long sides of the triangle as seam allowances. This gives you the front triangle insert. Cut a rectangular piece of powernet 2-3/4″ wide, by 2″ shorter than the length of your bra back at center back. This gives you the back insert.
Baste your powernet/techsheen bra front and backs to the wrong side of your bra lining front and back pieces. You will treat them as one layer from this point on. Right sides facing, sew one long side of your triangle insert to the cutout section of your bra front, using a 3/8″ seam allowance. Snip the center front of the bra down to, but not through the stitching line. And here’s where I’m going to make it easy to get a perfect V. With your bra top right side up on a flat surface, fold the seam allowance of the unstitched side of the opening under 3/8″. Apply Washaway Wonder Tape to the seam allowance. Making sure that your powernet insert triangle is laying smooth and flat, peel off the backing paper and press the folded under edge of your opening onto the powernet. You can baste that side into place, or just trust the Wonder Tape to do it’s job. (Although I am a big believer in basting, I trusted the Wonder Tape and it held fine until I was ready to topstitch all my layers.)
Right sides together, and lined up at the top edge, sew the rectangular powernet insert to one side of the bra back. Line the insert up with the top of other side of the bra back and stitch, using 3/8″ seam allowances.

Sew the front and back bra pieces together at the side seams. Sew the lining front and back bra pieces together at the side seams. Note: the pattern calls for 1/2″ seam allowances, so be sure to use this seam allowance on the side seams, even though I use 3/8″ seam allowances on the rest of this hack. Fold the center back edges of the bra lining under 3/8″ and baste.

With the bra right side out, and the lining wrong side out, place the bra lining over the bra. Line up the neck and arm openings, and pin in place. With right sides together, stitch along the armscyes and add the elastic in the seam allowances as per the pattern tutorial. Stitch the front and back necklines leaving openings at the shoulders to add straps. Cut two pieces of bra strapping 6″ long. Slide a strap down inside each shoulder opening at the back, and with the end of the strap flush with the opening, stitch the straps in place. You may want to go over the stitch line twice to ensure that the straps are secure. Turn the bra right side out. Ensuring that the triangle insert and cutout opening are properly aligned, top stitch around the triangle.

Lining up the edges of the back and back lining so that they are even with the rectangle insert, top stitch along the edges.

Now you can try on the bra, and adjust the length of the straps to fit. You may end up cutting a couple of inches off, but you need long enough peices to work with! Slide the ends of the straps down into the openings at the front shoulders, turn the top wrong sides out, and stitch the straps in place at the front shoulders.
Sew your tank front and back bodice pieces together. Then slide the bra down inside the tank with right sides together, and matching center points on the front and back, stitch. Using the measurement in the cut chart, wrap a piece of elastic around your underbust to check for fit. I used 1-1/4″ wide sport elastic, rather than the recommended width. Use whatever width of elastic that works for you, or that you happen to have on hand. The elastic should fit snugly, but not uncomfortably. Overlap the ends and stitch together. Mark quarter points on your elastic, and at the seam allowance, and pin together at those 4 points. Stretching the elastic to fit, zig zag it in place. Turn the hem of your workout top under 3/4″ and use a zig zag, twin needle or coverstitch machine to finish.
Smile, and go for a walk or run, or hit the gym or yoga studio in your fun new workout top!

I bought all of my fabric, the Circular Knit, Supplex, Powernet, and Techsheen from Phee Fabrics, along with the clear elastic and bra strapping. The consistently high quality makes and keeps me a repeat shopper!

You need that extra width to make your drawstring casing, and for your skirt to have a little bit of ease. The skirt back should also match the curve of your briefs and have the same extra width. Because I’m tall and have a booty, I added a little extra length to the center back of my skirt, tapering up to the side length. It’s just enough to cover my bum when the skirt isn’t gathered up on the sides. Sew the skirt front and back right sides together with a 1″ seam. Make drawstrings by cutting four 1-1/2″ wide strips of fabric twice as long as the side seam of your skirt. Fold each strip right sides together and using a stretch stitch sew with a 3/8″ seam allowance. Use a safety pin or bodkin to turn the strips right side out.
Fold the bottom hem under 1/2″ and use a zig zig or other stretch stitch to hem. On the right side of your skirt, make a small horizontal slit in each casing, about 3/8″ above the hem. Thread a drawstring in each casing and tack the drawstring in place at the top.
Align the center front, center back, and side seams of your brief and skirt and pin or clip in place. Try it on to ensure everything feels comfortable and lines up nicely. This is your opportunity to trim the rise a little bit if needed for better alignment. Easing the skirt to fit the brief, baste them together. Then sew on your waistband and elastic and you’ve got a new swim skirt!



You’ll need to poke one side of the back through the narrow space at center back to turn the back right sides out. Then it’s time to sew your side seams. I hate bulky side seams, and with the straps, and elastic, and layers of fabric and powernet the seam could get bulky! So I do it a little differently than you may have seen. Since the front strap casing is folded down at the top front, my normal method of sewing the main front to main back, and lining front to lining back, lining up the top seam isn’t going to work.












My Scrundie swim bottoms were a success, and I have a cute new swimsuit! I love that it’s modest enough, while still being sexy. My husband definitely approves of my creation!

I cut out two 4-3/4″ x 7-1/2″ rectangles for my front pockets. I wanted them to be hidden seam pockets like the one I did on the
I flipped the pockets back to the outside edges after stitching and basted them in place.
At this point, I should have been able to sew the tank front and back together, and sewn the bodice to the tank. But I had made a couple of rookie errors. 😦 The first was that I had made the tank too wide at the top. This was easily remedied by angling the tank in at the top so that it was the same width as the bodice (and the original tankini pattern piece.) The second error was not considering the fact that I am tall, and should have added an inch to the length of the tank. The problem was remedied easily enough by adding a band. I cut out the band pieces, and sewed them onto the bodice per the pattern tutorial, except using a 3/8″ seam allowance, and spacing my bodice front center V only 1/2″ apart. I don’t want to show too much skin at yoga class!
I brought the outer band down and basted it in place before attaching the tank portion. I sewed on the tank, hemmed the bottom, and I’ve got a cute new workout top!


I used a strip of powernet 1.5″ x 4″ to make my center back strap loop. I folded it in half lengthwise, and sewed it with a 3/8″ seam allowance. I turned it right side out, made a loop, slid it inside the center back opening I had left in the bra, and stitched it in place. Then I sewed 1/4″ clear elastic in the seam allowance along the top of the bra using a zig zag stitch. I stretched it slightly from the side seam up to the bra front points. I also stretched it slightly along the center front from point to point.
Stitch one end of your strap in place at one of the bra front points, turn the bra right sides out, string the strap through the loop and try it on. Adjust the strap length to fit you comfortably, while still feeling supportive. Then turn it inside out again to stitch the strap at the appropriate length, and trim off the excess. I think I ended up cutting a couple of inches off of mine.
Because I didn’t want the center front tie, I just made a gathering stitch down the center front of the bra top, and stitched my gathers in place with a zig zag, followed by a stretch stitch to ensure that my gathers stayed in place even with the frequent wearing and washing my workout tops get.
Then I cut a 6″ triangle out of my powernet. You can use the triangle you cut out of the bodice, (adding 3/4″ on the two sides to give yourself a seam allowance) as a pattern.
















If the lace and circular knit were an exact color match, I would have just used one layer of fabric for my skirt. If you’re going for sheer and sexy, you could just use the powernet.
When you sew the side seams together, sew all layers at the top and bottom for about an inch, leaving the middle 2 to 3 inches of just the front bodice lining free so that you have an opening in the side seams.

Then turn your bodice right sides out and press. Don’t forget to press all seams open as you sew. This helps reduce bulk when sewing your layers together, as well as giving your garment a more finished look. Cross the bodice fronts over as per the pattern markings and baste in place. Pin or baste the straps in place and try on for fit. You may want to shorten your straps or move them closer to the center. Maybe you want to cross them in the back. The best part of sewing is that you make garments that fit YOU. Once you’ve decided on strap placement, stitch the straps in place. Lining up the bottom edges of your bodice main and lining fabrics, baste the layers together. This makes it easier when you sew on the band.


Other than the straps, I sewed the bra together per pattern instructions. While I love the look of the double straps, they are more time consuming to construct. So I still cut out four strap pieces, but used them flat (as main fabric and lining fabric) rather than as double straps sewn to each shoulder. I used powernet in my straps rather than adding elastic.
Once you’ve sewn your main and lining pieces together along the top, try the bra on, adjust the straps to length, then push the straps through the openings and stitch.
To avoid bulk, be sure to trim the seam allowances at the back strap openings on an angle before turning the bra right side out. It’s important to press as you sew. It helps everything lay more smoothly, and gives your projects a more professional finish. See the difference pressing makes between the left and right straps in the photo below?
The Lille body was wider than my bra. If I were making the body out of Supplex, and wanted it more fitted, I would have slimmed the top of the body a bit. Since I was going for a drapier fit with ruching, I just matched up my quarter points and eased the body to fit the bra.
I could have added a band with elastic on the inside at this point, but wanted to try something else. I used 3/8″ swim elastic cut to fit me at the snug yet comfortable length (just like you would trial fit the wider elastic in the band). I overlapped the elastic and stitched it together making a circle. Then I matched up my quarter points, and zig zagged the elastic to the seam allowance. After that, I flipped the seam allowance toward the bra, and top-stitched it in place.
To ruche the sides, I cut two pieces of swim elastic a couple of inches shorter than my side seams. I zig-zagged the elastic to the side seams and ta-dah, instant ruching!
When I go to the beach to get photographs in my makes, sometimes silliness overtakes me. But we’ll just say I was jump testing the workout top to ensure that everything stays in place!
