I wanted 400cc but my doctor said he could only fit 325cc. That doesn't seem right. Could he have gone bigger? (Photo)

With your history of larger breasts previously in your life- I am not sure why you did not get what you wanted. Your photos seem to indicate more than adequate amount of skin in order to accommodate the larger implants that you requested. 

Hello, usually it is possible to insert the implants that were requested in the preop consultation, but occasionally the tissue is too tight to accommodate the larger implants.  It is unclear why your surgeon would insert smaller implants unless they felt this was the only option.

There is no such thing as too large for you.  You in fact have a perception of what you want to look like.  The surgeon cannot tell you what you like.  It is as ridiculous as them telling you what your favorite color is or picking out your new car for you.  They can guide you, but if your perception and their rigid, non-scientific approach don't mesh, find another surgeon.The best way
to determine the size that fits your personal perception of the perfect breast
is to try on sizers. This way you can see how they fit on you, how they add to
your current volume, and whether they fit your frame. Although the surgeon can
guide you, only you will be able to tell what is the right size. Try on sizers.
HP implants, which are a more modern shape than moderate profile
implants, fit most women better. They have a more appropriate base diameter for
the average women's chest. Mentor HP profile saline implants have base
diameters that range from 8.8 cm (very narrow) to 13.8 cm (moderately wide).
The majority of women in my practice have base diameters in the 11 to 13
cm range. The HP implants fit them well. The moderate implants have
much wider base diameters for the same volume (often in the 14 to 15.6 cm
range). These implants are too wide for most women that I treat. So
when the base diameter is measured and correlated with the diameter of the
implant, it is most often necessary to use HP implants to achieve the volume
the patient is requesting. At the volume selected, my patient's base
diameters are too small for moderate profile implants. Measuring a diameter and
then telling the patient what volume they can have (in high, moderate or
moderate plus implants) in my mind is backwards. The patients should be
allowed to choose the volume. Then the surgeon carefully considers the
base diameter, projection, profile, manufacturer, and fill material that will
achieve the patients goals of size as well as qualitative look (natural,
intermediate, or bold upper pole fullness or projection), all the while taking
into consideration the patient's anatomic features that will affect the
outcome. HP implants can be made to look very natural or very augmented,
depending on where in the range the implants are filled to achieve a particular
volume. At the low end of the fill range, HP implants do not have the upper
pole fullness that most people associate with the fake look. On the other hand,
a fake over-augmented look can be created with a moderate profile implant if it
is overfilled (a common practice for surgeons that commonly use moderate
profile implants). In addition, too wide an implant will put the volume past
the anterior axillary fold, which in my opinion, looks more fake than upper
pole fullness. So there are many factors that need to be considered.
The experience of the surgeon and the degree to which they explain the
options to you is of utmost importance. Obviously all of my patients look
at photographs and we evaluate the look they are desiring in great detail.
For me, high profile implants are the first choice. I rarely find an
indication to use moderate or moderate plus implants. This does not make me a
better surgeon, or a worse surgeon. Look at the outcomes and judge for
yourself. The outcomes should stand on their own. The subtlety in
the final outcome is not achieved by which profile implant is used, it is
determined by the skill in the creation of the pocket, the choice of volume,
and where in the range the implant is filled. Don't let the doctor tell
you what would look good on you. They cannot tell what you perceive to be
the best size.
