I got 275cc implants placed submuscular, did I go to small?

At 3 weeks your skin and muscle will still be fairly tight. As it relaxes the implants may look a little bigger; you need to wait 3 months to see.

Patients often think in terms of cup size when considering augmentation. Unfortunately, devices are sized in terms of milliliters (cc) of volume. This can lead to some confusion when sizing. Additionally, it is important to remember that cup size itself is not standardized with variations from one manufacturer to another. Unfortunately, as many women can attest their cup size in an industry leader such as VS is not necessarily transferable to another brand.
A general rule of thumb is that 125cc can represent somewhere between 1/2 to a full cup size increase. Smaller volume differentials (25-50cc) are typically less consequential representing a volume change of less than a shot glass. However, I have found these numbers, at least anecdotally, to be of little help. Patients often present with notions/goals which do not correlate with these sorts of sterile volumetric assessments.

When sizing patients, there are a number of useful tools including:
-3D imaging (has the added benefit of offering a volumetric analysis of the pre-operative breast)
-Breast sizers (rice bags)
-Goal photos
I also recommend that patients commit to a particular look rather than a cup size. Once a patient settles on a look that pleases them the overall cup size increase becomes less relevant.The key to obtaining a natural result is to stay within the parameters defined by your BWD. This will ensure that you avoid the dreaded "fake" look. 
The question of "too big" or "too small" is a relative question. The safest approach is to stay within the boundaries of your BWD. I would recommend a measure of patience as it will take several months for settling prior to obtaining a final result.
As always, discuss your concerns with a board certified plastic surgeon (ABPS).

Hello, it's difficult to comment about appropriate implant sizing based on a description.   For example, 275cc implants might make a large difference if inserted into the breasts of a very petite person, but they might not make a major change in a very large woman's breasts.  I'd suggest waiting at least several months before making any judgement about your breasts because the shape will continue to change.

Hi there Emily,Thanks for posting. Everyone remembers the fairytale of Goldilocks and the 3 bears where Goldilocks is fretting over the temperature of her porridge, the size of her chair and the firmness of her bed.The early stages after breast augmentation is a bit like this. Sometimes they feel too big, sometimes too small but eventually they end up being just right. For most patients there is a fairly narrow range of implants that are "just right". Whilst a bigger implant may have some benefits, it may also have some disadvantages too.At 3 weeks it is too early to tell. It takes time to get used to your new size and appreciate what an improvement you have achieved.The   "boob greed" concept is real. Patients  can get themselves quite distressed  about what is often a trivial volume difference. I realise it is hard but try and be patient, get through your recovery and get used to your new breasts. Try and compare them to what you were before rather than what they could have been. In the vast majority of cases they will end up being "just right"Best wishesRichard

Congratulations on having undergone the breast augmentation procedure. You should be aware that a significant percentage of patients at your stage of recovery will feel that they are too big or (more commonly) too small.I routinely ask my patients to wait at least 3-6 months before evaluating the end results of the breast augmentation surgery. This waiting time allows patients to (usually) physically and psychologically adapt to the new body image. Many of my patients report that as the swelling around the breast implants (for example, in the sternal area) decreases, they feel that their breasts appear more projecting.  Also, in my opinion, the "drop and fluff” phenomenon does hold some validity; as breast implants “settle”, many patients feel that their breasts actually look larger. Although online consultants cannot predict whether or not you will be pleased with the long-term outlook, of the procedure performed, it is safe to predict that the breasts will change. 
 Best wishes for an outcome that you will be pleased with longer-term.
