Breasts with a broad root are breasts whose base is broad. By base I mean the part of the breasts that is attached to the torso. You can visualise such breasts as cones with a broad circumference.
It is not always easy to identify broad breasts on a photograph or in the mirror, as the proportions of the rib cage can make the breasts look optically narrower or broader. However when you try on a bra, you can usually tell if you have broad breasts -- narrower underwires (like those of Freya, Lepel or Comexim bras) cut of a part of your tissue, and you seem to need underwires that end at least in the center of your armpits, if not further.
To help you understand how broad-rooted busts look like and the fit issues that they face, here are some photos of breasts with a wide root. Don't forget that broad-rooted breasts come in many different shapes -- they may be big or small, shallow, pendulous, firm, unfirm, bottom-heavy, top-heavy, wide-spaced or not, and so on. Even the broadness of broad roots differs: some are slightly broad and can still wear some Freya underwires, others are very broad and need to focus only on brands and models that have wide underwires.

Bust A
The owner of this bust is 5'2" tall and weighs 185lb. Her current measurements (that seem to fluctuate quite a bit in the bust) are:Underbust:
- loose: 39"
- snug: 35"
- BTT: 33"
Bust:
- standing: 49"
- laying: 50.5"
- leaning: 52"
"Not a smooth line from armpit to waist; instead, a bulge of tissue below the armpit because breasts are wide enough to wrap around the sides."

"A slight crease can be seen sloping down from the back of the arm pit to just under the breast."
![]() |
![]() |
"No Discernable Breast Root". In this case try the "Push Test":

"Some creasing seen where ill fitting bras sat, and towards the back." |
"Tissue falls from around the widest point of the ribs rather than from the front of the ribcage."
![]() |
"Too big in the band so no wire distortion. The wires are quite wide and accommodate my breast width beautifully. If only the cup and and fit :) " |
![]() |
"Slightly too narrow wires that dig in to the side boob spillage at the underwire tip just below the end of the channeling." |
![]() |
Bust B
Her measurements:
Underbust loose: 35
Underbust tight: 33.5
Bust standing: 44
Bust leaning: 48
"In addition to being very wide, I have a lot of migrated tissue back towards my shoulder blades that I'm still working on bringing forward. I spent a lot of years wearing bras that were 4+ cup sizes too small, so I have a lot of tissue that needs to be brought back to where it belongs!"
This is what she looks like in her best fitting bra, an Elomi Valentina in 34HH:
"This bra is one of the best that I have, and the wires encase my breast root pretty well, although you can see in the naked side shot that there's still a bit behind the wire. You can also see how my root is pretty flat on the bottom and angles up a bit towards the side. So far Elomi bras are the only ones I've tried that have fit well (and made me feel good about myself), although I do have one Cleo that fits okay, although I can't wear it for more than about 8 hours before it starts becoming uncomfortable."
Bust C:
Her breasts have broad roots and are also shallow. This can make finding a well-fitting bra hard, but she doesn't give up and instead chooses to try to modify fitting bras.
Measurements: underbust: break-the-tape tight, fully exhaled: 29.0" comfortably snug, fully exhaled: 29.75" bust: standing: 35.25: 90 degrees: 37.0" laying: 36.5"
"Here are my broad roots! You can still faintly see the marks from the bra I just removed, but I’ve highlighted the inframammary fold in orange. It goes pretty far into my armpit! I have pretty classic shallow boobs, with tissue spread out all over and up almost to my collarbone, but veryy little projection. I usually wear a 30 E/F."
"This is a Freya Ivy longline in 32E. The red line shows the wire, and the orange line shows where my inframammary fold. You can see the wire is a bit too narrow. It’s actually worse than it appears, because this is at least one cup size too big (it looks huge on my right boob, but that’s my smaller boob). So in the correct size the wire would be way too narrow. It’s also got too much projection for me. Luckily I was able to fix both those problems!"
"Here’s the fix! I basically took a little tuck in the top of the band just past the end of the wire. You can just see the little fold in the photo. This has the two-fold effect of opening up the wire so it fits my root, and flattening out the cup so it no longer has so much projection. Note that this only works if the wires are pretty compliant, like they are here."
"Here is the modified version! Now the wire follows my root quite well, and the cup fits better too. You can see there’s less gapping on the top, though there is still some on the right boob.":
"Here’s me in the famously terrible Cleo Jude, in 30F. The cups fit terribly in multiple ways, but one of them is that the wires are quite a bit too narrow. This is what the bra looks like before I’ve swooped and scooped. Once again, the orange line is my inframammary fold. You can see the wire is sitting on my boob."
"But here is what happens after I swoop and scoop! Since this wire is quite stiff and my breast tissue is quite firm, my boobs basically force the wire down my chest. It’s a similar idea to the orange-in-a-glass problem, where too-big boobs will leave empty space in the cup because the base of the breast is too big to fit into the cup. Here the root of my breast is too wide to fit between the ends of the wire, so it leaves some empty space at the bottom of the wire."
"Here’s another picture of the extra space at the bottom of the cup. Sorry it’s so blurry!" |
Hopefully this posts helps you to establish whether your breasts have a broad root or not. I want to send out a huge thanks to the awesome ladies who submitted their photos for this post. Thanks, you rock!
Do your breasts have broad, medium or narrow roots? Which is your preferred bra brand? I'm on the wider side and like the underwires of Panache (and their daughter brands), Masquerade, Ewa Michalak and Affinitas bras.

I 32E mostly and I have very similar shape, so from my experience: the best bra ever is Mimi Holliday Super Plunges (If I were you I would go for 30F in them may be even 30FF in certain colorways, Berry Fest runs especially small, e. g.), some Fauve halfcups might also work (but go for smaller size there), I tried Lucia and it it was fab, but it was sister size in bigger band, so I haven't bought it, and I was unable to find it for the reasonable price in the colorway I like. Masquerade Tiffany is also good, but it discontinued, although you can find it on ebay.

My width comes primarily from my wide rib cage - my breasts are centered, close set and I don't have much side-boob at all. I'm pretty deep at the mid/low line...so Panache and Cleo works well for me in a PLUNGE (the close set thing).
Great post, thanks!

Maybe if she was very slim she would be a D; but, she is the weight she (currently) is.
Not some kind of, fictional, ideal weight.
Also, you don't have to be overweight to have a large root size (or underweight to have a small one) - many women who are very slim, also, have larger roots.
Even if we assume that she should be wearing a 38 band (because, let's face it, it looks so perfect on her!), rather than a 34 band (as it looks so tight) she would still be predicted to measure around an H cup, with her declared 49" overbust measurement.
You, typically, add one cup size per one extra inch your overbust measures, above the underband measurement (starting with an A).
So, as her overbust measures 11" over 38", that is 11 cup sizes; which is a UK H.
Actually, it's not quite that simple, as people obviously vary; but, it gives you a rough idea.
...and in fact, we know she is above an H, as the 38HH she has tried, although appearing very close to perfect, in every other way, is still (slightly) on the shallow side.
The fact that she is, probably, nearer a 37" underbust measurement (if taken reasonably snug, but not too tight) and that she has slightly elongated breasts (which will add a little extra flesh to the cup, once uplifted), probably explains why she is slightly above an H, in reality.
Not to mention that the specific brand and/or model may have slightly less volume, than average, for an 38HH cup.
By the way, the adding 4 thing is now a little outdated, even if you prefer a looser band (as I do).
Generally, that would now result in a too-loose band, with many brands.
I think adding 2", or even going with your actual underbust, now makes more sense - but, obviously, not if you pull the tape so tight that it's cutting right into your flesh!
Which it would appear the first girl probably was, as her "loose" measurement (of 39") is 4" more than her "snug" measurement.
There should not be anywhere near that much variation.
I believe they, originally, added 4" for two reasons:
1. Because a 36" bust was considered ideal. So, they added 4" to the sizes, so that a 32" underbust (or less) woman would feel better about the size she was ordering. Ironically, this now seems to have reversed. As women now realise it's referring to the underband, not the overbust and so, many want to order bras in their actual underbust size. Or (apparently), sometimes, even less than that...
2. Because the original fabrics used for underbands didn't stretch as much as some modern fabrics do. So, adding a few inches, for comfort, made more sense.
If they only add(ed) four inches, for much larger band sizes, what you are saying might make some sort of sense.
Although, even then, it would leave taller women (who are, inevitably, going to have larger measurements, even when not overweight) out of the equation.
But, they don't/didn't.
They add(ed) them for all sizes.
Even for very small band sizes; which would, often, be used by underweight people.

You get 80% of your support from the band, do off you measure 32, then you need a 32. Adding 4" makes no sense. Would you do it with your trousers?
Women know that the old way of measuring made no sense, and are starting to find new ways of measuring that make sense (now shops need to catch on). The reality is that 36a/b and C is a rarity and 32FF is a common size.

You don't, necessarily, have to be able to see a crease to know breast tissue is there.
Women can feel where their breast tissue ends and an underwire laying on top of it, or digging-into it, can be extremely uncomfortable.
Especially with a tight band.
However, I totally agree that the answer for her is not to buy a relatively large-cupped, underwired bra, with no real way of filling it.
The answer is to either go with a non-underwired bra, or a bralet, for a more natural look.
Or, perhaps, to go for an air bra-type padded/push-up bra.
In the case of the latter, they generally come with wider wires (sometimes, far wider) than the size they are intended for and a pocket for the removable pads.
Which could even (presumably) be replaced with slightly larger pads, if necessary.
Huit make great air bras.
So great, in my opinion, that I buy them and then remove the pads and use them as regular bras!
Nouvel Emoi are the best for me - I measured the 36DD one and it has a size 50 wire.
So, it uses the wires for a typical 36G bra, but made to fit a 36DD (with pads in place).
Sadly, I think they may be in the process of discontinuing it, which is a great shame.
Might not be the best model for this girl, anyway, as it has quite a lot of projection; which might not be possible for her, even with the pads.
But, they also do other models, with far less projection, which would probably work well for her.

And FYI, soft bralettes don't tend to work well for my shape - I just fall out of the middle!

I would never, ever wear my band that tight.
With those measurements, I would have put the first girl at a UK 38HH (or a 38D7).
Definitely not a 34 band, of any cup size.
That is why the beautiful bra, in the 38HH, looks so good on her (if slightly too shallow in the cup) and is not causing the horrific distortion to her torso shape that all the 34s are.
She should have just tried a few more 38HHs, in various brands/models, until she found one with a little more projection. :)
Or, possibly, risked going up one cup size in that design (if available).
The extra 8mm, or 9mm, that would have added to the wire size would, probably, not have made that much difference to the excellent root fit and the slightly larger cup would have, probably, been the perfect volume for her. :)
The second girl's choice of band sizes (including her "best fitting" bra) look even tighter on her than the first girl's 34s and they are ruining her (naturally smooth) body shape and making her look bigger (and far lumpier in the back and waist etc.) than she actually is.
I understand (as a busty girl, myself!) that women don't want to have to just keep on going up back sizes to, finally, find the right wire/cup size.
Especially as, beyond a certain point, that can compromise support and comfort.
However, there is such a thing as too-small/tight band sizes, as well and that can be just as unflattering and uncomfortable as too-small cups are.
