The Making of The Little White Bra

My last post was an introduction of sorts to my current project: The Little White Bra, a.k.a. The Bra Before Dyeing (or just “Before”). Now, since this was the first time I’ve used this bra pattern, I’ll show you how I made it, including a few changes I made.

My pattern is Kwik-Sew 3300— I’m being adventurous and trying my first partial-band bra! For those of you who might not know the difference (and I’m not sure I noticed it myself before I started making bras), partial-band just means that, rather than a continuous band running all the way around the bra, including under the cups, the band comes around from the back to attach to the sides of the cups only, with a small bridge piece connecting the cups in the middle, like so:

The Little White Bra I just made, using Kwik-Sew 3300, View A with the lace upper cups and bridge. (Click the photo to see this pattern on Kwik-Sew’s site; right now it says it’s temporarily out of stock. Boo.)

Because I was already planning to dye this bra after sewing it together, the most important part of planning was to choose dyeable fabrics. Lest this sound terribly obvious, the truth is, if you just go by the scanty instructions on many dyes, you might get the wrong idea about the types of fibers you can dye with them. I have a lot of experience with dyeing yarn, mostly with acid dyes, which are suitable for animal fibers and nylon, so for this project, I’m aiming for as many nylon-based materials as possible. Some, like the back closure and the flower embellishment, have less than 100% nylon, so I anticipated some parts turning out slightly different shades. That’s okay— I’m not really going for a spray-painted look.

Note: I’m not going to show every single step of making this bra in detail here; I’m focusing more on the things I did differently than the pattern. Do let me know if you have questions about this pattern and/or project!

  • Upper cups: 1 layer stretch lace + 1 layer non-stretch cup lining
  • Lower cups: 1 layer Swiss dot (stretchy mesh fabric) + 1 layer non-stretch cup lining
  • Bridge (between cups): 1 layer stretch lace + 1 layer Swiss dot + 1 layer non-stretch cup lining (I used all 3 layers for extra stability here)
  • Bands: Power net fabric
  • Channeling: Plush-back channeling
  • Straps: 5/8″-wide strap elastic (moderately stretchy)

Here’s everything I’m using for my first LWB:

Materials for the LWB
1. Sheer non-stretch cup lining. 2. Rings & sliders for straps. 3. Flower embellishment. 4. 4″-wide stretch lace. 5. 5/8″-wide strap elastic. 6. Swiss dot stretch fabric. 7. Picot elastic trim. 8. Heat-sealed back closure. 9. Underwire channeling. 10. Power net fabric. Not shown: underwires.

After tracing my pattern pieces, I’m ready to start cutting, beginning with the lace:

Cutting lace upper cups
Here’s the upper cup pattern piece on the lace trim, which has been folded and the scalloped edges aligned so the top edges of both cups will match.

You know I love a good mock-up! Actually I only started doing this when I started making bras— it is really helpful for visualizing how things go together, especially when you’re working on something unfamiliar. Here’s my first layout:

First LWB mock-up
Since this is my first time making this pattern, as well as my first partial-band bra, laying it out like this helps me understand how the parts fit together. (By the way, you really can’t tell in this photo, but the cup lining pieces are there, behind the upper cup and lower cup pieces. And there’s a layer of lining and a layer of the Swiss dot fabric under the bridge.)

The first thing I’m doing is attaching the cup lining to the upper cups. This is different than the pattern, so I’m showing you here what I did:

Lining the upper cups
First, I zig-zagged the cup lining to the lace (1), then trimmed the excess from the top of the lining to just barely above the stitching line (2). This cup lining does double duty as a stabilizer for the upper edge of the cup (please note that this is different than in the pattern instructions).

After stay-stitching the lining pieces to the lower cups and remaining sides of the upper cups, I sewed the upper and lower cups together, pressed open and topstitched these seams, then started working on the bridge. This is different than the pattern too; the pattern specifies stabilizing the upper edges of the cups near the end of construction, but I’ve already stabilized these edges with the cup lining material, so I’m going to sew a seam (right sides together) to join the top of the lace bridge piece to the 2 lining layers (1 cup lining, 1 Swiss dot); after stitching, I turned the piece to the right side:

Sewing the bridge
After sewing the seam at the top edge, and turning the bridge right-side out, I stay-stitched all 3 layers together, about 1/8″ from the edge.

Tip: Here’s the thing about sewing that seam at the top of the bridge: it means the bridge piece won’t come up as high on the cups when I sew the bridge to the cups. This was only an issue for me later, because when I put in the underwires, they came up above the top of the bridge, creating a small gap.

Bridge gap
There’s excess length in the underwire channeling here; the arrows are pointing to where the underwires will actually end. So sewing that seam at the top of the bridge means that there is a gap there.

From this point on, the only other thing I did differently than the pattern was that I used strap elastic, rather than making my own straps from fabric. I also slightly altered the placement of the strap at the back band; instead of having the straps go straight down to the band, I wanted a slight angle, to make the straps less likely to fall off my shoulders (I hate that). Here’s how I did that:

Angling the strap
Here, I’ve pinned a strap in place on the back part of the band, to create an angle rather than having the strap go straight down from the shoulder. I’ll baste the straps in place near the top edge of the band.

And here’s my custom-angled strap after the first stitching pass to apply the elastic trim:

Applying trim over strap
Now you can see the slight angle of the strap. I’ve sewn the first pass to apply the elastic trim, over the strap; the second pass will be the 3-step zig-zag, as you can see on the finished lower edge of the band. I’ve placed the closure here, so you can get a sense of how close the strap is placed to the center back.

Remember that gap created by sewing the seam at the top of the bridge? Here’s how I dealt with that (and may I just say, “Ha!”):

Bridging the gap
Although I actually liked the look of the underwires extending up past the top of the bridge, I decided to use my little flower embellishment to bridge the gap. Good example of “mistakes” being the mother of creativity!

Here’s a look at the back of my finished bra, giving you a good view of those angled straps:

Back view of finished LWB
Even though the angle of the straps where they meet the band is fairly small, I think it will help to keep the straps on my shoulders.

Ta-da! Here’s my completed Little White Bra:

My first LWB, done!
It’s done! I’m almost regretting that this bra is destined for a dyeing experiment— I really like my LWB!

Next in this series: I’ll show you how I ombré-dyed my Little White Bra!

UPDATE: Kits to make this very bra are now available!


The pattern is Kwik-Sew 3300, View A.

The flower embellishment, power net, and Swiss dot fabric came from my local fabric store, Mill End.

The heat-sealed back closure, plush-back underwire channeling, strap elastic, and non-stretch cup lining all came from ArteCrafts.

Underwires and rings/sliders are from Sew Sassy. (Sew Sassy also carries Kwik-Sew patterns, and this is where I found my copy of this bra pattern, but checking there today, it appears to no longer be available.)

  1. I think it turned out delightful! I love the lower look of the bridge and the flower tie in! I like this pattern. How did you find the other kwik sew pattern you’ve done, the one with the seam in the bridge, to be different to this pattern, and which one did you prefer? Elaine

    • Well, the obvious difference is that one is full-band and the other is partial-band. And it’s hard to make a fair comparison because the full-band one turned out to be too small. I followed the pattern recommendation to use my RTW bra size (36DD), and both the cups and band were small enough on me to make it uncomfortable. So I decided to go up to 38DD for the partial-band style, and it fits me nearly perfectly! The only thing I would change is bringing the underwires a little closer together at center front, but that’s it!


  2. Thank you for including such detailed instructions. I have been working on this pattern. I used lace for the cups but did not line them — there was my problem. Everywhere it says the cups should be made of firm material or rigid lace. I’ve been trying to make them of stretch lace for a little more comfort — but I have not been successful. Any suggestions. Thank you. That was a beautiful bra you made.


    • I know what you mean about using the stretch fabrics— maybe we’ve just all gotten so used to everything stretching that we’re having to adjust to wearing rigid fabrics. But I’ve also found that the bras I like the best are the ones that have the least stretch; I just find them more supportive. Also, being able to stabilize a stretch fabric so it can be used for bra cups really expands your fabric choices!

      You’re asking for suggestions, but I’m not sure specifically what you’d like suggestions about. May I ask if you’re a larger cup size? I ask because I’m 36DD/E myself, and so support (i.e. rigid fabrics) is really important to me, but if you’re on the smaller side, maybe that’s not such an issue. But you do say that you haven’t been successful with stretch lace, so I wondered. Of course, the major issue with using rigid fabrics is fit; we all probably have to do some trial and error and tweaking of patterns to get a custom fit.


  3. Did you just use underwire channeling in this bra? Or did you actually use underwires in this bra? I know that with partial band they usually require the use of an underwire but I’m just curious.


    • There are indeed underwires in this bra— everything I’ve read says that partial-band bras MUST have underwires, and, considering the way they’re constructed, this makes total sense to me.


  4. How did you attach the underwire channeling? I can’t seem to find a tutorial on the internet anywhere that shows how to do the underwire channeling in a partial band bra…


  5. Just gorgeous. I so want to jump in and try…but just so afraid of failure…lol I know , I know….what could happen? I would get started.


    • Hi Carol! Believe me, I completely understand your feelings. I’d been sewing garments for nearly 50 years before I plucked up the nerve to try sewing bras! If you have any experience at all with sewing, I say, give it a try! The fit is, of course, the biggest issue, but the sewing itself is really not very different than sewing a garment, with 2 exceptions: (1) lingerie typically uses 1/4″ seam allowances, which takes a bit of getting used to, and (2) the way elastics are applied can be different than for garments. Try it! And let me know how it’s going for you!


    • Hi, Anna-Marie! I do not share patterns here, but I always share links to where you can find them. My suggestion would be to check out the Bra-Making Forum on Facebook (; they have tons of resources there including bra patterns (some of which are free), as well as expert advice on anything having to do with bra-making. It’s a fantastic group that I highly recommend.
