What cup size do you think this is? (not an obscene photo)

user746016 · 03/12/2025 08:14

Hoping that the picture won't get blocked (it's just taken from the skims website). I am about to have a breast reduction for medical reasons and am struggling to visualise what the various sizes will actually look like - clearly I appreciate I'm not going to look like the model!!

In my head this is about a C?

Im trying to see what a B would look like. I'm a size 10.

Yes, I think this is it. Surgeons are not bra fitters, I don’t think it’s useful to talk in cup sizes with them.

Talk size, volume, position, shape etc, and show pictures of boobs (preferably bare boobs, not in underwear, as it can be very misleading, as above.)

Then just get fitted once the op is done and everything has settled and healed.

He's the one talking in cup sizes.

Have you got Instagram? Try this, it’s real women in bras of all sizes
I would say your photo is a DD depending on band size

The woman who runs this account is awful! I had to block her because she harassed me in DMs for questioning her bullying comments on TikTok!!

Wjdbxb · 03/12/2025 10:41

My guess would be 28DD/30E as she has a very small frame so is probably a size 6 or 8, and her breasts are fairly big compared to her frame (although not big in the great scheme of things!) it’s going to be hard for you to let them know what you want as people without knowledge of real cup sizes would guess that photo as a C but when you actually know the science of it you know that the cup size is higher than that… but I doubt surgeons go by that, so goodness knows what you’re supposed to ask for.

OtterlyAstounding · 03/12/2025 10:41

Here's a TikTok of a woman with a 32B sizing https://vt.tiktok.com/ZSfn4kY1D/
It's a small size, but I can imagine you'll love it once you've adjusted! It's not flat and seems really practical – easy to go braless.

I'd ask your surgeon if he can show you the size in terms of a sample implant, or photos of other patients. Cup size is very unhelpful, I think.

It usually tells you in the product details what size and height the model is.

I just checked. Under ‘Fit & Fabric’

  • Sarah Is Size 2, 34B, And 5' 10” (178 Cm), Wearing SKIMS S

I would have thought larger too, but the other pictures of her side profile, she looks much smaller busted.

skims.com/en-gb/products/naked-plunge-bralette-clay

That’s because she isn’t a 34 anything.

34B=32C=30D=28DD approximately. And often they stick them in a cup size or so smaller to make their boobs look a bit more voluminous.

SpidersAreShitheads · 03/12/2025 11:01

I think the problem is, as a PP said, there are two distinct methods of measuring breast sizes now.

I range between D and DD and have big breasts so it always sounds strange to me when someone uses the new method of measurement and says they have small breast but are a DD or larger!

With such disparity among the methods of measurement, plus the differences between UK and US, I’m not sure this post is going to help you that much.

Is your surgeon able to give you more objective info on breast size - for example volume in mls? I don’t blame you for not wanting implants.

I would expect the surgeon to be describing things in line with the old style of bra measuring so to be crude, a B would be a small handful?

34 is simply the size in old money. Size 34 fits a 30 inch rib cage.

Buying from a bra retailer like M&S that sizes in old money then a 30 inch rib measurement is a size 34. The same measurement in a bra retailer that sizes in new money is a 30. They’re both made to fit a 30 inch ribs.

This simply isn’t true. Modern bras are made of stretch fabric. They are measured un stretched. I wear a 30 in both m&s and Freya for example.

I measure 35 ribs and wear size 36 M&S bra, that isn't made to fit 32" ribs, so it can't be sized the old way or I would need a size 40

lindyloo57 · 03/12/2025 13:16

To help with volume i have breast implants size 360cc I wear a 34 D im a size 12 I didn't have hardly any breasts tissue of my own, I use to wear a AA cup the smallest,
Hope this helps. For the who say I'm wearing wrong the size, I have tried 32 back measurements my measurements but can hardly do them up.

That’ll be because the cup size is wrong.

Wouldn’t it be better to ask your surgeon rather than ask folk to guess on the internet?

Bras have been made of stretch fabric since the current sizing was introduced in the 1940s. I have some of my grandmother’s underwear. The idea that the old +4 did not account for stretch is just untrue.

What has happened though in the last 40 years is supersizing of population and vanity sizing. Women’s clothing has downsized by a couple of sizes. In the 80s & 90s I was 8-10. Now I’m 4-6 for exactly the same measurements.

I’m 28 ribs and wear a 32 in M&S.

I do see women wearing bras with band sizes too small so they cut into back fat.

lindyloo57 · 03/12/2025 14:06

@TulipTuesday I've heard this before but I put my bras on doing it up at the front and 32s are so so tight, I can't breathe, so how do that mean but cup is wrong when I haven't put the breasts in at that point.

Tammygirl12 · 03/12/2025 14:07

30D or 30DD looks similar to me

eqpi4t2hbsnktd · 03/12/2025 14:31

I would have said a b cup...

This is where I struggle to understand sometimes
I’m a solid size 18 and wear a 34 band! I wore a 32 at a 14/16

Bigger bands sometimes make back fat worse, there’s an article on it somewhere but I can’t find it right now
basically my back fat makes me look like I have back fat and if I wore a bra big enough to not squish it, I wouldn’t have any support at all

BobnLen · 03/12/2025 15:23

Fortunately I haven't got back fat, unfortunately I do have large protruding ribs which looks like a double set of boobs if I wear something fitted so do need a fairly large band even though I'm not overweight to accommodate this.

lindyloo57 · 03/12/2025 15:55

@bodyofproof I don't understand it either, maybe brands fit different, I wear mostly m & s the none wire ones, I did have a 34 DD from John lewis but had to put a extender on as it was too tight. I measure 32 under the bust and 37 over. I'm bony under the bust can feel my ribs but do have a little back fat,

Helpful, thanks.

I obviously spoke to the surgeon but have been a bit more focussed so far on that fact that he's having to chop half of my boobs off. He said it will be a B cup. Fine - I made a note of that to look it up but I'm now realising that when you look online at what is a B cup you get vastly varying pictures.

CarefulN0w · 03/12/2025 16:19

I think you need to know what your surgeon thinks a b cup looks like. Most men including breast surgeons, underestimate and think a D cup is large.

If you can bear the conversation, and it isn’t two sexist, handfuls might be a more useful guide.
