375cc or 400cc Moderate Plus Breast Implants to Get C Cups?

It doesn't matter which size you choose, as there is little difference. You could put one on one side the the other on the other side, and probably not be able to tell the difference. Pick a size and don't second guess yourself.

The question
of breast implant size is always difficult for prospective breast augmentation
patients.For this reason, multiple
approaches are utilized to make this determination preoperatively.These include reviewing magazine photographs,
external sizers, and recently the 3D Vectra computer imaging system, to name a
few.Even when tremendous care is taken
preoperatively to determine breast size, the final decision needs to be made in
the Operating Room, by the surgeon.At
this point, an assessment can be made regarding how the patient’s breast tissue
interacts with the breast implant.Occasionally, obtaining a specific size doesn’t allow the surgeon to
meet the patient’s other aesthetic goals.For this reason, locking into a specific size isn’t always a good
idea.Results are often better when a
surgeon has the ability to make adjustments in the Operating Room.It’s also important to realize that,
for many patients, a 25 cc difference in breast size would be difficult to
notice.In reality, a 25 cc difference
is less than two tablespoons, which is spread out in three dimensions over the
implant.In your case, I think it’s important
to thoroughly discuss your aesthetic goals with your surgeon.Make sure he has the latitude to do what’s best
for you in the Operating Room, so he can meet your aesthetic goals.It’s important that you have an approximate
idea of the breast size that you’re considering, but don’t become married to an
absolute number.

I would need to examine you but 12.5cm usually is 350cm, if you were stretchy I would add 60cc if your skin is tight I would reduce 30cc

You've decided on a plastic surgeon that you trust to do your surgery. Opinions from us without having seen you are worthless.  If you are still having doubts go on another consultation.

Hi there-
I agree with my colleagues that there would be no perceptible difference between the two implants you list...
You should also realize that micromanaging these decisions is not in your best interests... choose a surgeon carefully, communicate your goals well, and then trust them to do what they do.

There really is no difference between those two implants. You are talking about 1 shot glass equivalent in a 12 shot glass bowl. So as you can see there is not much difference between the two sizes.
Your plastic surgeon will decide in the operating room as to the exact final volume, but you are pretty much there.
Good luck and enjoy.

25cc barely fills a shot glass of Tequila. At least here in Texas. Remember that your surgeon needs a little room in surgery to choose what looks best on you.
I won't let my patients choose a specific implant size, but encourage them to select a size range that meets their desires.

It might be helpful for you to recognize that 25 cc is less than 2 tablespoons, and cup size is a highly variable way to measure breast size. It is based on the size of the chest as much as the breast, and the final breast volume is implants plus your exisitng breast tissue. Best advice is to forget about cup size and try sizers on to see what looks right. Your surgeon can then determine which implant will give you that look (it will probably be slightly larger than the sizer).

The truth is that there is basically no detectable diffference between 375 and 400cc. The difference is two tablespoons and probably less than the variation in size that you commonly experience with a menses. Typically, in the average A cup, a 350cc implant will take you up to a full C cup. However, I have had patients with smaller implants go up to a D so it truly varieys by individual, clothing preference and designer.

Hi Sadie, thanks for your question
on which implant size would be best for you.
Right now it sounds like you’re considering 375cc and 400cc. Since there is no way to say definitively
over the internet which size would be optimal for you, take comfort in the fact
that the surgeon uses your unique measurements and is able to provide you with
a general range. In many cases the board
certified plastic surgeon can best be your guide as they’ve met with you in
person and heard your aesthetic goals. You may consider doing 3-D imaging;
however with nearly all the breast cases we’ve performed, we’ve found patients
enjoy doing a live “try on” session where they actually can “try on” the
implant in a non-padded bra in our office.
This does not give an exact measurement of outcome, rather it gives a
nice idea of what to expect. For patients who desire a more natural look we
like to recommend the shaped implant.
For patients who desire a more full, voluptuous look we recommend a
higher profile implant. And remember that all breasts have at least some amount
of asymmetry (we like to say they’re like sisters and not twins). My very best to you. – Dr. Brian Coan
