Australia’s Lingerie Blog for Women D Cup and Up

Myth No.2 – DD cup is huge

Using the term  ‘DD cup’ excites the boys and frightens the girls, but mention you are a G cup in polite company and people will look at you in disbelief.

These women have been fitted into D & DD cup bras in various back sizes. Do they look huge? No they don’t they look perfectly lovely. This is what real D & DD cups actually look like.

Many, many women think they are D cup and always seek that size, but when they submit to a proper fitting, D isn’t even close.

At Brava it’s not unusual to fit a woman who says she is 14D into a bra that is 10G, it happens all the time. She looks and feels much better, but is often shocked and maybe in denial about her correct size, in fact sometimes we dont tell her. Isn’t it all about how she looks and feels, not about the numbers on the label? We’ve seen women who refuse to wear the correct bra size and continue to squeeze themselves into D cup – maybe this is a new phobia – this fear of wearing D+ cups. ‘Deecupphobia’!

Contributing to the confusion are images of celebs like Pamela Anderson with reports of her being 36DD (14DD) after breast augmentation surgery. She is a tiny framed woman with full breasts and is more likely to be a 30G (8G).  The size 36 (14) band has nothing to do with the size of her breasts. Does her ribcage look like a size 14 and would she wear sized 14 clothes?? Definitely not, she looks like a size 8-10 to us.  This is just one of the reasons people see DD as so big.

YouTube images of women with larger cups are often hideous and mostly designed to tantalise morons. If you look around at your colleagues and family, many of the women will be bigger than D cup but chances are they are wearing a badly fitting D cup that makes their breasts look bigger and their grooming a tad scruffy.

The cause of this phenomena no longer exists.  For a long time DD was the largest cup size made and people perceived this size as very big. Many women wore DD in a bra that had a band much too big for them, it rose up at the back, the cups werent smooth, the shape was distorted, the support was totally inadequate and the comfort level was abysmal.  In those dark days there were no other options unless you could afford to have bras made for you, or took a chance on having them altered.

There are no excuses now, innovative lingerie manufacturers are designing fabulous D+ cup bras that are supportive, beautiful, high quality and affordable.  The size range won’t be in all lingerie shops and department stores, for a variety of reasons, but the really good specialist shops have the finest off them. Working with many large cup lingerie brands and ranges from around the globe, they test them on themselves and their customers, they review them, decline many and only stock those that do a sublime job of supporting women.

We shouldnt be telling you all about the sizing issue without providing some explanation of how bra sizes actually work to give a better understanding why a D cup is not necessarily a big cup size. Did you know:

  • D cup on a size 10 band (10D) is 3 times smaller than a D cup on a size 16 band (16D). The equivalent size of a 10D cup in a 16 band would be 16A.
  • A 12G cup is the same size cup as a 20DD
  • An 8J cup is equal to a 14GG.
  • Generally D cup augmented breasts are measured from a 16D mass, so on a size 10 frame it will look more like an F cup – most surgeons do not take into account the band size of a bra which results in a huge misconception. So when you see these very busty size 10 ‘D’ cup girls post augmentation they probably have equal  to a bra sized F cup on their chest.

Confused?  The D cup changes in size along with the band size. If you have been wearing a 12DD and we fit you into an 8F, this does not mean your bust size is bigger, it simply means you have been wearing a band that is far too big for your frame. But sometimes all a woman can see is that letter ‘F’ and for her that stands for freak, but we see ‘F’ for fabulous.  Still confused? Ask us a question.

    I’m 19 in a few days and I’m a 10L. I was a late starter to get boobs as I was a national athlete, training every day. In the last 11 months, I’ve gone from a 10C to an L!! I’m struggling to find bras that fit me! Surely there is somewhere I can buy decent bras from? Size 12s do not fit me as they are too large around the shoulders and rib cage. I’m nearly out of an L cup and haven’t found any bigger bras! Where do I go from here? I can’t afford a breast reduction yet!!

    • The Bra-Fitters says:

      Hi there Casey! Quick question, are you using the Australian cup sizing or European cup sizing? The European L cup is equivalent to the Australian JJ and you can find plenty of great bras from us at For the Australian sizing, there aren’t many brands around that produce cup sizes an L cup or larger in smaller band sizes unfortunately. I would recommend taking a look at Ewa Michalak’s website ( – they currently produce bras up to a LL cup and we find them a great fit, especially in the larger cup/smaller band combinations. I hope that helps!

  2. Keiarn says:

    So I’m 16, and I was just fitted today, before hand I thought I was a 10E and now I’m actually a 10G, what are the size differences and what are some good shops to shop at in nsw Newcastle and hunter region area?

    • The Bra-Fitters says:

      Its great you have been fitted correctly now. The difference between 10E to 10G is 3 cup sizes – which happens often when you’re re-fitted. I imagine it feels much better? Our stores are in Melbourne, so we don’t know what is available in your area, but you may like to shop online at

  3. Rikiardio says:

    Which Bra size is bigger 10e or 14d?

    • The Bra-Fitters says:

      Hi Rikiardio! The 10E and the 14D are actually the same size in the cup! This is due to the grading difference in the band size – so while the cup sizes will be the same, the 14D will be longer in the band than the 10E. I hope this helps!

  4. Molly says:

    I’m a 14E but I feel like it doesn’t fit properly in all the right places but never really get good advice from anyone else, please help.

    • The Bra-Fitters says:

      Hi Molly,
      I’m so sorry to hear that your bra doesn’t feel like it’s fitting properly. If you’re in Melbourne, I would definitely recommend that you come into one of our Brava stores to be fitted correctly. If you can’t make it in, we have heaps of fitting guides that you can look at . Many stores will not stock bras with cup sizes larger than a DD or E – unfortunately these stores will often give you a bra that is too big in the back in order to make the cups fit which usually is pretty uncomfortable! The most likely problem that you’re experiencing is that the back band is too big; if possible, try a size 12 bra with an F or FF cup and see if that makes a difference. Best of luck! – Kellie

  5. Olivia says:

    I’m 14 and I wear a size 36ddd in Victoria secret. Is this considered big and are Victoria secrets sizes different?

    • The Bra-Fitters says:

      Hi Olivia,
      Thanks for your comment. We get many people your age in our stores being fit for bras that wear anything from a D cup to a K cup. Every size is normal, so wearing a 36DDD is not unusual at all! Victoria’s Secret sizing I believe is a little bit smaller in the cup than other brands I believe. I hope this helps! – Kellie

  6. AJ says:

    I’m 12 and 34dd. Because my mum isn’t amazing to go bra shopping with, I had to get measured myself but I had no advise, so is this normal?? Thanks for taking your time to read this 🙂

    • The Bra-Fitters says:

      Thanks for your comment, AJ. Any size is completely normal, and everyone develops at a different rate. The best thing to do would be to get professionally fitted. I know it can seem intimidating especially if you don’t have a parent to go with, but bra fitters on the whole are a lovely bunch and you need to make sure that you get the support that you need. Best of luck! 🙂

    Hi I have very large books that finding pretty bras has become difficult. I am unsure about purchasing online because I don’t know exactly what size I need current in a 14 F but also have a 16 j in a different style the full cup 14 F feels like it provides more support. I’m currently wearing breastfeeding bras but when I stop breastfeeding I want new bras as don’t plan on more kids. Can u send me some advice on finding the right fit online I don’t wanna spenda lot of money and get the wrong size.

    • The Bra-Fitters says:

      Hi Kim!
      We know how difficult it can be to find something pretty beyond a D cup, plus we also know that sizing can be tricky to get right, especially with the changes that come with breastfeeding. It might be that the 14F feels more supportive because the band is firmer – I would guess that the 16J is too big in the back and cup for you right now. I’d recommend taking a look at our bra fitting guides at and our returns policy for online purchases allows you to receive an exchange or refund on anything that you’re not happy with, plus we’re always available for fitting advice.
      I hope this helps, but please don’t hesitate to let us know if you have any other questions at all!

    Very interesting article! I’ve recently been fitted as 12H. Would be interested to know the equivalent in sizes 14 & 16. I have quite a few older bras and I thought that after having my second bub (still breastfeeding) that my boobs were massive but may be same or even less than before pregnancy & feeding.

    • The Bra-Fitters says:

      Hi Jen!
      If you’re currently wearing a 12H and the cup is fine but you’d like to change the back size, you could try a 14GG or a 16G – these are exactly the same volume in the cup, just with a looser band. If you need a smaller band size, you need to go up a letter in the cup to get the same volume, and if you’d like a larger band size, you need to go back a letter to get the cup size right. I know it’s really confusing, but I promise it all works out! Let us know if there’s anything more you’d like to know about equivalent sizing!

    Umm hi! So I’m 19, I live in California, USA. I just found this site today. It is a bit confusing, but helpful. Ever since I was little I was always a larger cup size then the other girls in my class. And now at almost 20 I’m a 44H, fitted by myself. But I’m not sure that I’m in the right size or not. I’m a bigger gal too. So anyways, I was wondering what you all thought. Over looked at charts before and measured myself, and they say I’m supposed to be a J? Because my breasts measure about 10-11 inches over my ribcage. Thanks so much if you do reply. c:

    • The Bra Fitter says:

      Hi Maddie,
      Thanks for your message. Its difficult to get the right size with a chart and tape measure because all women are unique, size, age, firmness, shape etc, only a proper bra fitting with an experienced fitter can ensure you have the right fit. I suggest you go to our website and look at our fitting guides, its about following the steps to work out if your current best fitting bra is feeling secure and comfortable. Sorry I cant help more. kind regards Maxine

    This has made me feel so much better about my recent bra dramas! I’ve been wearing a 10DD for about a year, and over the last few months feeling extremely uncomfortable. I finally went and got fitted, turns out I’m an 8F! I was pretty distressed about being so big and ‘disproportionate’ but i feel better after reading other people’s comments! Is there anywhere in Tasmania that stocks Brava?

    • The Bra Fitter says:

      Hi Alice, Thanks for your comment. 8F – not disproportionate at all, only the bra size makes it sound that way. Plenty of girls are your shape but unfortunately so many lingerie stores still don’t get it. Sorry Alice, we bring these brands in from overseas suppliers so we don’t have a Brava brand that we supply and we do not have a store in Tasmania. We can help you to purchase online or maybe you can visit us one day, just email kind regards Maxine
