Are C Cup Breasts Too Big for an Asian Frame?

Thank you for the question.

It will be extremely important that you communicate your size goals with your plastic surgeon. Your definition of “C cup breasts” may differ from that of other people. Also make sure you are  communicating your (not your boyfriend's)  goals.

In my practice I find the use of goal pictures to be very helpful.  I have found that the use of words such as “natural” or “C cup” or "fake looking" or "top heavy" means different things to different people and therefore prove unhelpful.


Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup  size may also be inaccurate.
I use  intraoperative sizers and place the patient in the upright position to evaluate breast size. Use of these sizers also allow me to select the breast implant profile (low, moderate, moderate plus, high-profile) that would most likely achieve the patient's goals. The patient's goal pictures are hanging on the wall, and allow for direct comparison. 
I have found that this system is very helpful in improving the chances of achieving the patient's goals as consistently as possible. 


I hope this helps.

I am not sure how to answer this question. Given your measurements, I do not think that a C cup os too large.

Most women, at least in my practice, who come for augmentation want to end up in a "C" cup.  At 5'7", I think you would look fine.  As thin as you describe, I would recommend silicone gel implants.
