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.
