FINISHING JERSEY KNIT
by Daughter Fish
Last summer, I spent a few weeks making (and singing the praises of) maillots—a.k.a. unitards. Ballet and modern dance classes were a huge part of my adolescence, and my maillots remind me of the comfy ballet unitards I wore back then. Of all the garments I’ve sewn over the past year, I think my maillots have gotten the most wear. This chevron tank top—which is really just a muslin/test garment—is the next evolutionary step of my maillot pattern.
Like my maillots, this tank top has a built-in shelf bra. For me, a one-stop bra and shirt is the ideal summer garment: super comfy and easy to wear. I usually like to sew cups into my shelf bras, for more shape and support (and to avoid the dreaded “tube boob”). Unfortunately, I was all out of cups for this tank, so it has more of a sports bra look to it (which I will remedy with some cups on my next version).
When I was sewing the tank, some annoying rippling happened where I sewed the neckline of the shirt and shelf bra together. My regular machine isn’t so hot on sewing jersey, and I’ve yet to find a double needle that will leave clean rows of top stitches. Generally I just sew two rows of top stitches with a regular needle. This time, though, the feed dogs pulled too hard, stretching the fabric, and I got gaping at the neckline.
Lately, I’ve been trying to push myself to finish garments in a clean way, with really good fit, so that I’ll actually wear them. I tore through a lot of sewing projects last summer that have stayed hidden in my closet because of bad fit or shoddy workmanship. I was learning, so it goes with the territory. But I feel like continuing down that path, at this point, is a little too fast fashion-y and antithetical to why I want to make clothes for myself—i.e. wearing quality garments that are made just for my body, and that express my personal style. So I’m trying to take things more slowly (take more care), and pay attention to details. That meant I needed to fix the gaping issue on my tank.
I’d already finished the tank’s arms and hem with simple bands , so I decided to try this around the neckline. It took me some time to figure out how to make the mitered corner on the V neck (I spent a good hour staring at the guts of my husband’s store-bought V-neck T’s). I also found this Threads video on a neckline binding for knits SUPER helpful . The trick to getting a nice binding that hugs the body (and doesn’t gape) is to stretch the binding along the curved edges of the neckline. This technique would have prevented my armscyes from gaping, as well (domage! I’m not tearing those suckers apart now!).
Now I’m excited to try a version of this shirt with a lower, more dramatic back line. I also want to experiment with making some fancier versions (maybe with cut-outs of sparkly spandex? Similar to my Sparkledex Maillot).
If you’re interested in drafting your own version of a maillot (or a tank) based on my pattern, check out my brief tutorial.






Great fix! I often add some narrow clear elastic to my neckline edges (folded over or bound) to avoid this, but it really varies a lot by fabric, doesn’t it?
I think I NEED some striped knit to get some chevroning action going… >_<
I’ve read about the clear elastic fix. I’ll have to try that. And YES you do need striped knit. You would rock the chevron!
Fantastic save! It’s a great detail, too. I love the simplicity of a built-in bra for summer, but I never feel supported enough… maybe cups would help? You know how the Burda mags always call for vilene/pellon bias tape? Well, after sleuthing, I found some, and it’s so perfect for preventing sag/stretch on knits! It’s a narrow fusible bias tape that has stitching down it for stabilization.
Vilene/pellon whaaaaat?! I’m getting some! Thanks for the tip!
So lovely and figure-flattering! I was inspired last summer to copy your chevron maillot style (sans shelf bra). When you sew cups in, promise to show us how?
I loved your take on the chevron dress last summer (it was in orange, as I remember, one of my favorite colors!). I will definitely do a little tutorial on the bandeau bra with cups!
Great shirt! I need to make some like this for my girls this summer….
Oh, yes, do! They’re fast to make and fun to wear.
What a gorgeous top! I love the chevron effect. Thanks for posting the link for the sewing with knits tutorial – sometimes I just want to pull my hair out with all the gaping! Your neckline looks fantastic – the back is positively fabulous!
I really like that tutorial. The same teacher has a few more on the Threads site!
This is gorgeous! Who knew that knits could be chic?! I love it! I really like the look of the narrow band on the neckline.
Thanks! I love the knits:)
[...] super proud of how I finished the neckline on this dress. I used the same technique as for my chevron tank, with fabric bands around the neckline and arms. For the pattern, I simply elongated my maillot [...]
I love that first photo, the movement and the disappearing!
And I’d love to have to try your maillot, because I’m determined to get my tanks right this summer. (I fiddled a lot last summer with my own draft.) Just this very morning I was on the way to the gym in my little top with shelf bra and thought–why don’t I have regular non-gym tops with shelf bras? Bras are so annoying in the summer (for me).
It’s taken me awhile to get that neckline binding thing right and it behaves so differently on every fabric.
[...] are way too good to last. The heat, my friends, is coming. In preparation, I’ve been sewing summer tanks (with built in shelf bras with cups!), like the striped one pictured up [...]
[...] The shirts and maillots I’ve been making with built-in bras came from a similar, practical need: I want to wear low-backed shirts without tacky bra straps. It’s been exciting to see that many other home sewers like this idea, and in many cases have perhaps already thought of this but have yet to try it. The great thing about sewing blogs is the constant exchange of information and ideas on how to make patterns or techniques better. And I’ve gotten a few great ideas on my built-in bra technique from some of you this past week. [...]
