How bra sizes work

For example, a 34D bra cup is nearly identical in size to the cup of a 36C or a 38B bra. However, the 34D bra fits a woman with a smaller bone structure compared to the frame of women who wear the larger band sizes.

You have to try it. Very good recommendation, thanks! We can model a boob as a cone. How do bra sizes scale up?

Bra sizes that are the same in volume are often referred to as “sister sizes”. The grey cells in the table below demonstrate how the sizes diagonally adjacent from the top right to the bottom left are the same in breast volume i.e. the same volume of breast tissue spread across different size rib cages (band sizes).

Most women think when they find a bra size that fits in one bra that will be the size they are in all bras but every bra style, size, colour fits differently, a white bra in a 36h will fit differently to a black bra in the same size, same style and brand.

step Measure your Band size. With your bra on, measure firmly around your rib cage, directly underneath your breasts. The tape measure should be horizontal around your body and should not drop in the back. This is your underbust or band measurement.

I like this post. I was recently sized to a 34 DD, my original size was 34 D since my breasts were too big for a D cup. Well only because I slouch. But yeah I love this article. Where did you get measured for the 34DD? Breats are beautiful any size. I love dd or e but you get what how you love. Just like men you get what size you get and thats it. All girls are beautiful no matter what size there breast are.

I have to say this post makes me feel a lot better. I was shocked and not one of my friends believes me aside from the one that was there with me and saw me try it on. I live with three well endowed busty girls who are all slight in stature, and their Ds are protruding and bulbous.

I went for a bra fitting only recently as I was sure they would have nothing for me as I have tiny ones. I was so happy to find out there one nice bras out there even for me! When I called Bravissimo their customer services was lovely told her my measurement and said that was a 40d which sounded huge recommended several when they came they were too small in the cup spoke to Bravissimo again offering me a fitting in one of their stores who fitted me as a 40dd.

Still a bit shocked each time I pick up a 36hh bra as it does look big but tried one of those 40dd bras and it gives me double quad boobs. My measurements are 33 for my underband and I know its all relevant to the band and all but that sounds too big to me.

Is there any advice you can give me? Hi Shelby, thanks for stopping by to comment! Have you had a look at the Bra Band Project? These ladies all wear a 34F , and these wear a 34FF — do these look around your size? It may also be that you have a shallow shape to your breasts which mean that they are less pronounced from the chest and more widely spread, so they appear smaller by sight.

It would be worth trying a few bras around a 34F or FF to find out what will fit you best, and bear in mind that the shape of the bra may not always be right for you. Any advice on what to do here? What are my possible bra sizes? Okay, I done the measurements and it said that my closest bra sizes were 40D, 42C and 44B. Do you know anymore places that can accomodate those sizes without having to go online and fork out loads of money for a custom made bra? I will even go slightly smaller if I have to.

Hope this is helpful and you manage to find something comfortable! Very good recommendation, thanks! Love the bras in your pictures! By the blue and pink one, do you mean the first bra in a 28GG? I believe that one is a Cleo Melissa. Panache also do some 38Ks — see a couple here at Very. So is there any sizes anyone on here could suggest trying? My boobs are extremely saggy which is why I usually stuff myself in too small of bras but again, when I tried looking at bigger sizes they are always too big to do anything but sit on my chest..

At the moment, you may not be getting enough support when you try larger cups as the band may not be tight enough — trying a 40 band may help with that. Hope that helps a bit! So many people have the wrong idea about bra sizes, and their jaws drop when I tell them I am a 32G. Ah well, one day! Also, I will be able to wear bralettes???! Not in my wildest dreams a year ago..

And hope the little cup reviews are helpful to you too! I feel maybe I should just purchase a few larger sizes on some internet sites to get a realistic feeling of what may be true to my size.

I disagree with the idea that anything bigger that a triple D is fake. My best friend is only seventeen and overflows her e cup bra. Any advice due her situation?

I also wore overflowing E cups at 17, and now wear a 28GG and am very happy with it — the discomfort I had is pretty much gone! These bras are all available in up to an L cup, and look how pretty they are! Your article was fantastic! I was just wondering if you could help me, I have a 32d bra size but I wear a 36c which is just very slightly big for me, is this a bad idea?

Thanks so much for your help! Hi Lana, thank you! Where D cups are too big, are unattractive. All I want is for people other then disgusting perverts want to have a relationship with me.

But all the normal people seem to hate big cup sizes: Hi Haylie, please please please read the post first before commenting and leaving! I was also a similar size to you at age 13, wearing 34Cs and 34Ds, but then I discovered I was more than likely in the wrong size.

And wearing the wrong size can make you feel bad about yourself. I am a man so it was just out of curiosity. In a sentence although this may make it more confusing! This clarifies a lot, advertising and the media has fed us so many lies!

This was so helpful. I recently got fitted for a bra after wearing a 36B for most of my boob filled life and was shocked when the woman at the store told me I was actually a 32D! This whole event kind of blew my mind and made me research bra sizes.

Your page helped a lot. She even went and looked up how bra sizing works and agreed that band size and cup size are relative, but that a D would still be huge.

I think she may be a lost cause. It was really uncomfortable and I was always embarrassed to ask my Mum to measure me, but yesterday I finally had the courage to ask her and she took my measurements and put them in online and it came up as me being a 32DD. I honestly started laughing and asked her how I could be that size considering my boobs really do look small. Hope the blog continues to help! Charley is a similar size to you though and finds that Gossard work really well for her and give her cleavage!

Did you use this calculator with your measurements? How do your current 40DD bras fit does the band ride up? Do the cups overflow or gape anywhere?

Do you find the wires digging in? I know the calculator can be a little off in your size range, but it usually provides a good starting point. You may end up surprised to find an F cup fitting — I know I was! Obviously size can be a factor in it, but usually you get the drop in tissue relating to size if you go up and down in sizes quite a lot ie.

Hope this helps a bit! I worked in a department store fitting bras for years, and I have so much I could say! I also wish there were more UK sizes and smaller bands available, some styles came in 30 but nothing smaller.

I was fascinated that I was actually a 30B, although we only carried one or two styles. But now several years later, I realize she was totally right! A difference of 4 inches, a D cup!

And yes, my boobs are still pretty darn tiny! I perused Amazon for a Freya and a Curvy Kate which should arrive soon. And I obviously wish more bras came in my size, but maybe someday! D is actually the small end of the spectrum. This website is awesome. Hi Jo, thanks so much for stopping by and for your lovely thoughtful comment! Thank you so much for this post and the blog! I actually got so upset about bras not fitting me that I wore only a binder for over two years.

I stopped wearing it only a couple of months ago. Although I wish Disney bras in my size existed just to satisfy my inner child. Hi Linus, so glad you like the post and blog! And with you there on the Disney bras! I read the article about the fact the most if us are in the wrong size bra.

I also measured myself first I was surprised to find that I too have been wearing the wrong size forever. I have been wearing 34Cs, 36Bs, only to have troubles with spillage over top, loose straps, side affects, not a good look. So, what did I do? Only to be disappointed with the results as usual. So to humor the girl I said I would go ahead and try on the 34D. To my amazement, suddenly all my stuff was contained! I have given all my old bras away and purchased several new ones in the proper fit.

Thank you for your effortsupport to educate us in the bothersome matter. It might be worth thinking more about it in terms of numbers rather than letters, so it simply means that your bust is 4 inches bigger than your underbust as a D cup whereas a C cup just means 3 inches difference. Hope this helps you feel a little better! Thanks for chiming in, Emma. Looking at them there is no way anyone would think that.

Before that I was wearing padded sports bras. The bra hurts because the underwire was sitting on my boobs and I was also spilling out the top and a bit on the sides. Sorry for replying again but I just wanted to mention my measurements. Hi Chloe, no worries! Do you have Nordstroms in Canada? That can also be quite good. The Butterfly Collection is also a Canada based website that sells a good range of bras but appears to be down at the moment. Aaa so you really think most of the celebs or pornstars who are bigger then D cup have fake boobs or was that just a joke for us people, the people who think that DD is the largest cup size and their is nothing after that.

Because by reading the comments and articles about this topic i can say their are thousands and thousands of bustier women with cup sizes bigger then DD. What do I do? That does sound to me like your bra cups are too small, especially if the band is resting on breast tissue — ouch! Char is our Little Cup but wears a D cup 30D , so it just goes to show.

Thank you for your article! I am 33 and went to get a bra today to wear with a new dress. They asked my size and I said 34 or maybe 36 A. A sales lady measured me right away, telling me I was a 34 C. I laughed and said I was possibly a B cup. Then I went into fitting room and tried on bras and was sized again and found out I am a 34 D! My mind was blown! So was the sales lady who helped me when I kept insisting I was an A cup. But today, when I put on the right sized bra, I felt amazing!!! Wow, we love getting comments like this!

As someone who is very small-busted, I was actually overjoyed at being told I was a bigger cup size. I was glad to know that I am a sister size to a commonly sold size—32A. I was also glad to know that even among women of the same size, they may prefer different bras bc of different shaping and spacing. I know exactly what you mean! Bras are crazy complex, two women of the same size could still fit best in completely different styles.

Unfortunately, in our 28 size range there are few options to choose from. Someday I will have more options I hope!! In response to scaling down, it really is hard to find bras for small frames. If I have to pull out one of my old 32A bras, I always find that the cup digs into the side of my tissue. Definitely not suited for wide set breasts. You can really see in my proper fitting 28D that the cup goes toward my armpit and holds all my tissue.

Their styles tend to have a LOT of padding. Also, they only go up to a C cup. I want to know how many women out there are actually wearing their AA and A cups.

I wish they would give up on the idea that a D is huge and make a couple more cup sizes. Do bras from the Little Bra Company work for wide-set breasts? I have to make sure that the underwires go out far wide enough though. On the other hand, women who are larger have more breast tissue that can be adjusted into the given shape of the cup more malleable, wider range of motion.

I do think that their bras tend to be more for close set breasts, like you noted. I would consider myself to be fairly wide set and have trouble containing the tissue by my armpit. Sometimes it helps to go up a cup size, but in TLBC this option may not be available. I would say the tissue by my armpit is pretty well contained but could still be better. The other styles I have tried on have been tiny in the cups and have given me too much spill out the top. So I have man boobs.

I was interested in a properly fitting bra. I have tried a few here and there and never quite found the perfect fit. So I decided to measure myself and I was astounded by the result. I used a few different bra calculators and I came up with 42DD! Can this be true? I do realize sizing is all relative but still…wow! Can you help me please. The back on my bras always ride up and the straps tend to dig in.

Any suggestions would be very much appreciated. It does sound like your band size is a little too big and your cup a bit too small, although it could be that your bras have gone a little worn over time. Thank you for replying to my question almost a year ago, lol. Thank you in advance. So yet again thank you! So glad this helped you! I used be like you and wear 34 ds in which the band was too big or 32 dds and my nipples would always come out.

I wore those sizes since I was im now 23 because the only stores I knew of had them. Other than the one time my mom took me to a local store and they somehow fitted me in a bra that was way too big. But I sucked it up today and bought a couple bras in a 30 f.

Hi, thanks for stopping by! It can feel very strange at first, but if you find a bra that fits you comfortably, it can definitely help. It might help you to have a well fitting sports bra then so you can carry on doing what you enjoy comfortably.

I need some suggestion. My friend is 32H. But it is very difficult to find the fitting bra for her size around where she lives. Whereabouts does your friend live? In fact, many bra stores and online sites STILL tell you that to measure your bra size, you measure around your rib cage below the breasts and add 4 inches to the number. This is the dumbest thing ever. I know it comes from bra designs of 50 years ago when the materials were all stiff and had no flexibility, so they HAD to allow some inches of slop in the band or the woman would suffocate.

But the old style of measurement would put that woman in a 40B, which is absurd. Im not a girl, so Im trying to get an understanding. This page is dedicated to celebrity bra size. You can see pictures of different actresses arranged in order of their bra size.
