DIY: How to make a bra strap converter for low-back dresses

Wearing a low-back dress? Extra Petite, Boston style blogger shares a DIY version of a bra strap converter. It's super easy and simple to do!
If you’ve ever passed on a low-back top or dress due to qualms about what bra to wear, here’s a quick DIY project that might nix such qualms in the future. After posting about a few holiday dresses this season, several readers (thank you all!) informed me about a low-back bra converter. It’s very affordable to buy, but not always easy to find right when you need it.


Thankfully, the converter design is not rocket science. The night before my event, I scrounged up some supplies at home and finished a bra strap converter on my own in 5 minutes. All you need is:
DIY Bra Strap Converter for Low-Back Dresses

1) Snip off the clasps from an old bra, making sure to leave enough “band” on to attach to the elastic. Bra clasps for the most part are universally sized, but do test out the clasps on the bra you plan on wearing just to be sure.

2) Sew one clasp to the end of an elastic band. Make sure you sew it on securely because there will be tension pulling on the band.

3) Clasp it on one end of your bra, and wrap around your tummy to measure the length you need. You want it to be taut so that the tension pulls the back of bra band down low enough, but not so tight that you’re uncomfortable. Cut your elastic to the length you need, then sew on the second clasp. Voila! This will not work on completely back-less items, but is adjustable enough to work on a range of lower-dipping backs.

A few of you have asked how the Zara sequin dress in XS worked out, so here is a belated update. There was once a time when I’d go for the tightest fit possible, but that time has long passed. The XS will work nicely for some, but on me, it was very snug and less flattering than the small. For reference, I’m about 5ft tall and 32-24-32.

I’ve mentioned before that I find clothing to be most flattering when it just skims your figure – and this is most evident in the side view comparison of these two dresses:

I did find the waist on the S to be slightly loose, and altered it last minute by making a small incision along the inner lining. There’s a zipper along one side of the torso (which I didn’t want to touch), so I took in the other side by about an inch, right at the waist line. The amount was small enough to not make the dress too lopsided, but enough to make a little difference in the overall silhouette. Photos above are post- DIY alteration.

    Awesome tutorial. I did perfectly and was so comfortable. I pulled the elastic down my pelvic instead of around my waist or tummy and it was much more comfortable. God bless you. Thanks.

  4. Hi! My dress is very very low. Will this work? Or do ineed to have the elastic longer?

    I wouldn't recommend for a strapless, because it would probably pull it down too much without the support of two shoulder straps.

    This is so helpful! do you think it would work for a strapless bra for a wedding dress though? or would it just pull the bra down?

    Hi! I just found this blog and fell in love. I am "extra petite" too and I love your tips! This is a great one, since I don't dare NOT wearing a bra, and I had to pass on some dresses because of the lower back and bra's showing!

  21. I love that you are brave enough to photo yourself with the bra on the outside of the garment. You are wonderful and so creative with your solutions. Genius, I say!!! And great reminder that even though the XS fit, the S was definitely more flattering and less hoochy. Great lil alteration you did at the waist!

    I just purchased the sequin dress in xs it was on sale online. I tried both the xs and s on. I maybe a tad bit smaller than you. The small is quite loose on the chest area waist and the skirt flared a little at the bottom. Hope I didn't regret getting the xs ones 🙂 btw I purchased the dress cause It looked great on you. And I waited till it went on sale glad they still have my size.

    I find that your attention to those little details helps us all dress better and understand proper fit. I'm now always on the lookout for the S curve and blouse gaping. And I'm realizing that for me, mid knee is the perfect hem, even if it means hemming just an inch to get it right. I often go thrifting and will pick up sizes that are per-vanity days. Now, I bring a tape measure and look for ways to DIY alter, per your awesome posts.

    I'm afraid that may wear out the elastic much faster than usual?

  36. I'm so glad I found your blog. I am also petite and just started my own blog where I'll be posting fashion and clothing items that I've sewn and altered. I have to agree that the small size looks so much better. I have also realized as I get older that tight, no matter how small you are, is not really flattering. Unless you are 5 years old. 🙂 Look forward to more posts.

  39. A belt usually helps for me. If it's a super silky skirt, I sew on a little velvet or other similar fabric along the inner waistband for a little friction, especially if I am wearing tights. That solves it for me! HTH.

    About the Zara dress and its fit… I'm actually quite surprised, because Zara's XS have always been a bit loose on me (and I'm saying that as a slightly curvier girl at 4'10" and fluctuating between 90-95), so I guess their sizing is bit erratic? Anyway, you look absolutely smashing in that dress and that bra strap converter? GENIUS! I know that I've personally hesitated or put down dresses because I otherwise had no idea how to conceal my bra. Thanks for yet another brilliant DIY, Jean! 🙂

    Totally agree. I love that you don't give in to vanity sizing and instead look for the most flattering fit. I can be guilty of it from time to time, but the reminder and evidence is right here: the S with slight alterations looks incredible on you! I also appreciate that you are willing to showcase true fit on your blog, so that the readers who don't live in a shopping metropolis can ascertain how clothes will really fit. I can judge how well an item will fit me based on your reviews. Thanks for blogging with integrity!

  59. I love that you recognize the fact that just because you can technically fit in a smaller size, it might not be the most flattering. I'm not petite at all (far from it) and I find a lot of helpful information, especially about fit and customization. I see way too many people who get excited because the zipper goes all the way on a dress or pair of pants, without realizing it's not at all flattering, and going up a size would actually make them look smaller. Thanks for reminding us it's not about the tag on the inside that no one else will see!

    I noticed that your waist line looks unbalance after the post alteration photo. Could it be due to the one inch incision at only ONE side of the dress? I personally have an imbalance waistline. Do u have any idea how to overcome this problem? My right waistline is straight down, while my left side is more like hourglass shape. I'm so sad :'(

  73. I gained quite a bit of weight this winter, so I was debating between the Small and the Medium. The Small was tight but looked sexy. The Medium was loose, but looked classier and could probably be worn again for classy events. I was going to get the Medium and get it taken it; however two Sales Assistants highly suggested that I get the tight-fitting Small instead. I hope my date likes it for NYE!
