I had 325cc 4 days ago. My breast look very small and out of shape. Maybe I should go to a 400cc? (photo)

Hello,
I know it seems like nothing happened. However, as time goes on your breasts will take shape as your soft tissue envelope expands and allows for implant projection and fullness in the lower pole. It is likely your surgeon was respecting your anatomic capacity limit, something that is done in your best interest. The vast majority of complications of breast augmentation are avoidable and caused by inappropriately large implants. Be patient. Best of luck!

Thanks for your question and pictures. The 325cc should increase you about 1.25-1.5 cup sizes. That would make you a full B or small C. Obviously, this varies between bra companies. Looking at your wish pic, you may need slightly more implant size. That being said, you really, really need to wait 3 months to make any decisions. There are many changes that will occur in the next couple of months. Interestingly, I noticed your wish pick has a complication. The implant on the right side of the picture has "bottomed out". This makes the nipple point upward instead of straight forward and the upper breast lacks volume. These types of implant placement problems are common. This is the main reason you would want to wait before increasing size. Let the implants settle and be sure they are symmetric before going through another surgery. Best of luck!BH

I am sorry to hear about your concerns after breast augmentation surgery. Your plastic surgeon will always be your best resource when it comes to accurate assessment and/or advice. 
Having said that, it may help you to know that a significant percentage of patients at your early stage of recovery will feel that they are too big or (more commonly) too small.
Generally speaking, breast implants will "drop" into the pocket that was created during surgery. The rate of breast implant "settling" may depend on factors such as size of breast implant pocket dissected, tightness of the overlying skin/muscle layers, and size of breast implant utilized. Normally, it takes about 3-6 months (for some patients longer) to see the final result. It is very common for one side to settle faster than the other.
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. 
In other words, it is much too early to evaluate the outcome of the procedure performed; your breasts will undoubtedly change over the course of the next several weeks/months.   The vast majority of patients with your concerns at your stage in the recovery process, turn out to be much happier two to three months after the procedure was performed.  Understandably, patients often experience significant emotional "ups and downs" around the time of surgery.
For example, 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. 
My best advice: rest,  recover, and exercise patience.  Keep in mind, that a significant percentage of patients at your stage in the recovery process feel that they are "too big" or "too small".  In the long run, once patients have adjusted physically and psychologically to their new body image, the vast majority of patients are very pleased.If in the longer term you remain displeased with your breast size, re augmentation with larger breast implants may be an option.  If this does become the case, make sure that you communicate your goals  clearly; the use of goal photographs and computer imaging may be very helpful in the communication process.Best wishes for an outcome that you will be very pleased with.
