Why do some 32Bs look bigger than other 32Bs?

The misleading issue with breast cup size is that there really is no standard of measurement.  You can have two women who wear the same exact cup size in different bras, but if they try and wear each other's bras, they do not fit right.  That is why it is very hard to tell a woman exactly what she will be after a breast augmentation.  Cup size is more of a range than a precise size, so keep that in mind.  I hope this helps.

Thank you for your question.  There is a lot of variability when it comes to the appearance of women's breasts.  Bra manufacturers use numerical chest circumference, and cup size letter, in the attempt to standardize women into particular sizes for easy shopping.  But a B/C cup in one company is not the same as a B/C cup in another, much like a 27 in one jean company will fit differently than a 27 in another.  Additionally, the way a woman's breasts will fill the cup will be different based on their anatomy, such as breast width, breast projection, location on the chest, gap between the breasts, and "mobility" of the breasts when placed in clothing.  No two women have the same breasts, in fact most women have differences between their own two breasts.  Not a straightforward answer, but I hope it helps. 

Bra sizes are often not accurate due to the difference in designers, material and measurement inaccuracies. When discussing bras it is the size that fits you best that matters most. That can be a B-cup in one brand and maybe a C or D-cup in another brand.

I had 2 patients once who both had similar builds.  Both had 600cc implants.  Both went bra shopping and called the office in tears.  One was "measured" at an upscale bra shop with a little secret and was told that she was a 36A.  The other was measured at the same shop and was told she was a 36DD.  They both wanted to be a C cup and that's what I considered them.  In surgeon language, a B cup is a breast that covers the width of your chest and is full in the top.  A C cup is the largest breast that fits on your chest unsupported by a bra.  There are small B's and big B's.  There are also C's that wear a B because that's what they buy.  If you look good, don't worry about it!

There is much variability between bra makers and how women wear bras. So expect some variability between individuals. 

If that isn't bad enough, many stores now use "vanity sizing" where the mislabel their bras allegedly to make you feel better about yourself.  Best plan is to abandon the sizes on the labels and go where you can try things on and use your own judgement.

Everyone is built differently, and bras are not all the same.  That is the best way that I can explain this. Good luck.

Breast cup size is a relative measure of the breast volume to the chest diameter. Some may wear a 32 but might measure out to a 34. Also the cup size will vary by the bra manufacture or brand, some more narrow and projecting others a flatter profile. Of course breast shape matters as some will naturally lack projection and upper fill,and here a push up can help. Your friend might also just be squeezing into a smaller size.

Breast size is very difficult to quantify. It's not an absolute size but other factors such as the percentage of breast tissue vs percentage of fat in the breast, the amount of ptosis (droopiness) as well as chest (rib cage) shape play a factor.

Thank you for the question. There is no standard among bra manufacturers when it comes to defining specific cup sizes. Therefore, a  "B cup"  made by one bra manufacturer may look very different than the same cup size made by a different manufacturer. For this reason, I ask my patients not to communicate their goals or judge the outcome of the procedure performed based on achieving specific cup sizes.In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. In bra sizers can be useful communication tools also. I have found that the use of words such as “natural” or "B cup" etc means different things to different people and therefore prove unhelpful. The use of computer imaging may be very helpful during the communication process. I hope this, and the attached link, helps.
