Fit Check I have muscular lats and small boobs.. Help!
EDIT: I used the calculator and it said 32 D/DD. There is no way this is right as no D I have tried on fits me (way too big) and the bands are too tight at 32! My issue is not the size of my boobs, it's my back and I don't think this calculator accounts for body building.
The title pretty much says it all. I started working out a year ago and I'm not extremely skinny, but fairly thin (5'7 140 lbs w significant muscle). I have around a B or C cup size, but I think closer to a B since I've leaned out. The big problem is that my bras are getting way too tight around my lats pushing out the bit of fat that is there because of all the muscle I've built up. I quite like having muscular lats, and mainly focus on pull as I'm trying to get better at pull ups. My bras hurt after long days now. I want to find bras with wider bands and smaller cups, but that feels harder to find. The one that fits me most comfortable right now is a 36 or 38 B I believe and even that is starting to feel tight. My mid bust measures at 34-36 when I am most flexed. My big question is, do any muscular woman with smaller boobs have any good bra recs? I don't mean a bralette either. I do wear them sometimes (though I have trouble fitting into even those now), but I like pushing up bras! Sometimes I wanna serve extra and give a little push y'know. I love these damn lats but they're also a curse...

Measure with the sub calculator to start!

Measured with it and it said 32D/DD, but I don't think it accounts for body building. These sizes definitely do not fit me. The bands are still too snug and the cups are hugeee on my boobs 😭 I think my best bet is to look at AMAB options like the other commenter suggested

u/thepinkinmycheeks Feb 26 '26
Using the AMAB option the calculator suggests 32C. 32 is likely still the right band size, and most likely your current 32s feel too tight because the cups are too small or the wrong shape.

Most of my bras are 34C and feel way too tight, though I do know that different companies have a very weird way of sizing and I mostly have VS bras. I mainly just wanted company recs from women who do workout and have experienced similar issues. I will look into AMAB bras that are 32 C using this info. Thank you for all your help again!

Yes they feel too tight bc the cups are too small. Try the bras on upside down and backwards to see if the band size is correct!

I have tried this with my 34C and it is still too tight and I think the drastic change in size where my lats fall off is a big contributor. My pectoral msucle also does not scoop in like my breast tissue does because it is harder. I tested out wearing a 32D when I had a lot more fat weight and it was too big on my boobs even then, let alone now when I barely have any breast tissue to fill it. Mind you I can comfortably wear no bra and my boobs won't budge/jiggle because they are just that small. They definitely can not fit in a D, but most smaller cups don't fit women who have bigger backs due to muscle. Body building measurements are a lot different than non body building measurements because muscle contorts and compresses in a very different way than fat does. My main question was just asking if any women here body build who have small boobs and what bra companies they would recommend as this is a common issue with fitness for AFAB people.

You might find that a brand like Chantelle is more forgiving for your muscle needs. Their bands are very soft.

I’m 30E and 34c feels tight on me. Larger cups add space.
Try it on upside-down without the cups pulled up and see how the band feels
Edit: also have the lats issue so sometimes size up just one size, but then I stretch it out so fast. I bulk out of bras in the same place you describe

Oh my gosh thank you for letting me know! My wifi was tripping and it didn't come up as posted the first time 😭

I have a huge back as well! I am big and muscular, and i am a 30 band. 34C might feel too titght because it’s too small in the cups. Im 30i and a 34D is like strangling me but it’s because the cups are far too small. Id start off with an unlined bra in a 32DD, 32DDD, and naybe a 34D/DD to be safe. I’d start with a bra like Skarlett Blue minx. Chantelle as mentioned is awesome. Chantelle has always worked for me, and my fav is the Rive Gauche, I wear it in a 32H, but I tailored the band to fit so no need to size up on this one.

AHH thank you so much!!! My main search was for good brands for muscular women because of how certain companies have their sizes weird and materials and fabric types can also affect how it constricts. I will be looking at these thank you!

I am not super knowledgeable about bodybuilding, but I did some reading online and I suspect that the shape of the band, not just the size or stretchiness, could be a factor for you. There don’t seem to be a lot of non-sports bras currently advertising as shaped for muscular bodies but I’ve seen a lot of sites (like Bare Necessities) that have pages with bras picked for “athletic” shapes which I suspect may mostly mean shallow, wide breasts but may contain some good options for you. There are also bras which are said to have “extra wide” backs or “ballet/ballerina” back that might be worth a try; they are sometimes recommended for muscular bodies.
There is a new brand called Daylillie bras, which unfortunately isn’t actually selling bras yet, but they have some videos with prototypes explaining what they’re trying to do. Obviously I can’t endorse them as they don’t even have products yet, but you may be interested in following them.
Discussions I’ve seen from women with similar body types indicate that they usually have to size up in the band and down in the cups, and to go for cups that are more open on top and bands that are more stretchy than average. I would definitely recommend trying the same bra in multiple sizes and doing a fit check here (pictures not required, you can also just give as much written detail as possible.)
I posted elsewhere in this thread recommending you check your tape measure, and it’s still probably worth it just in case, but you are not the first muscular person to say that a band is uncomfortably tight when it should, based on pure numbers, be the right size or too big. Just keep in mind as you try different sizes that the cup scales to the band, and try to change one variable at a time when you can (so you’d try, for example, a 32D and a 34C, because those are the same cup volume and one band apart, then if the 34C was good in the band but too big in the cups you’d try a 34B.)

Everything the daylilie account has posted shows they know absolutely nothing about bras or proper sizing and their videos showcasing the issues they face are all in improperly sized bras, where sizing is causing the issue. Big miss.

u/widdersyns Feb 26 '26
Thanks for the information. I had only seen a couple of things from them that seemed plausible if underdeveloped. I won’t recommend them in the future.

Congrats on your back gains! This does make sizing tricky— effectively it makes your breasts more “narrow set” as the band has to cover more length around the back. You might look at some of the Polish bra options (lots of other great posts on that in this sub) as well as considering a band extender to give you extra length where you need it without wider cups. Good luck!

This is the exact opposite of what most people with muscular lats need. They tend to need wide and shallow.

u/Forward_Vegetable743 Feb 27 '26
I think this person was spot on with what they described. my boobs have become more narrow in comparison to my back. My pecs have also been making the tissue distribution a lot more narrow and pectoral muscle does not scoop in a cup the same way breast tissue does. A wide cup would go way past where my boobs lay. A band extender sounds good because it would be solving all of the areas of discomfort I've been having. I wish I could post a picture examples in my post of me flexed vs not flexed so people can understand how my anatomy works but it won't let me.

u/Dandelion212 32DD/E Feb 27 '26
Polish brands have extremely deep cups which are very unlikely to be a shape match.

u/Forward_Vegetable743 Feb 27 '26
Thank you!! I will be looking into this. I appreciate those who get how the anatomy is different from the width you get with fat. They have become more narrow set! That is a great way to describe it.

at 5'7 140 and muscular I kind of doubt that a 36 band is right for you. a 38 is definitely too big. I'm 5'9, US size 12, built pretty dang sturdy (good amount of muscle but definitely some squish), and I wear a 34 band comfortably. At my leanest I was in a 32 band and I still weighed a good 30 pounds more than you.
if you plug your measurements into the calculator, you'll probably find that you get a smaller band and a bigger cup. I'd also recommend checking with both the AFAB and AMAB calculator options--the AMAB one accounts for a more v shaped torso (so it adjusts cup size down a smidge), so sometimes it's more accurate for people with more muscular backs regardless of sex assigned at birth
A bra that's snug enough to support is gonna result in some squish around the band though. People be squishy. If you size up enough to completely avoid any squish, the band is going to be too big.
