Thank you for your question.There is no exact answer to this question as it will depend on your chest circumference and body habitus as also the kind of bras you will be buying. For the average body built this appears to be 2 cup sizes increase. I would advise talking to your plastic surgeon who can examine you and also give you sizes to determine the size of Implants that you need to get the desired results.Good Luck !!!!!!!!!!!!!!!
There are no consistent bras or bra sizes, and more importantly, letters of cup sizes to not correlate to volume in cc's. In other words, 2+2=4, but does B+350cc=DD? (Yikes, flashbacks to math class) A lot goes into determining cup sizes. I would recommend trying on several sizers in a sample bra. Although I may recommend certain sizes for certain body/breast types, ultimately the most important factor is how YOU look and feel (not the letters or the numbers).
