Anticipated Size Not Achieved After Breast Augmentation

In my experience, if a woman wears a size 36 AB bra and would like
to be a C cup, which is the average size that women wear and the average size
bra that is sold, she needs a volume of approximately 350 to 390 cc to make
that change. This becomes less if she's wearing a 34 bra, because it has a
smaller strap size and the cups have a smaller diameter. A smaller diameter
implant would then be a volume of approximately 300 to 350 cc. In the same way
if she was more petite, maybe a double zero or size one and wore a 32 AB bra,
then to become a 32C cup she would only require about 250 to 300 cc.

It's not uncommon for patients to express concern about breast size in the immediate post-operative period. Multiple factors make it impossible to assess breast size one week after surgery.Several factors affect the size of the breasts in the immediate post-operative period. These include swelling of the breasts and surrounding tissue, muscle spasm and the healing process itself. These factors interact in a complex manner to create a rapidly evolving situation. It's virtually impossible to make decisions about breast size until the situation has stabilized.In some cases, it may not have been possible to place a larger implant at the time of the original procedure. During surgical procedures, it's not uncommon for surgeons to make compromises to obtain the best possible aesthetic result. In some cases, utilizing larger breast implants can cause conflicts with other aesthetic goals. For instance, having large implants might create an unnatural look, which may not be desired by the patient. It may disrupt harmony, balance and proportion with other surrounding structures.All of these concerns might place limits on implant size. In most cases, after a period of adjustment patients are happy with their breast size. Rarely, secondary procedures are necessary. For these reasons, it's important to maintain close contact with your plastic surgeon.

Thank you for your question. One of the most common reasons why women have breast augmentation revision surgery is to change size. It is very difficult for a plastic surgeon to commit to a certain bra size as there are wide range of bra sizes and styles out there. It is not uncommon for a woman to have different bra sizes with different bra stores/brands.
I spend a great deal of time emphasizing during the implant size selection process to try on different external sizers to narrow down the look and size they like rather than try to pick the size based on projected bra size.
At this point, if it has been several months since your surgery and you don't feel your breasts are changing much, then you can consider upsizing the implants. I would visit with your plastic surgeon so they can guide you further.
