Each woman has her own preferences when it comes to the ideal breast size, and it is okay to want a high and fake look. However, I am confused by you then saying you don't want to look too top heavy. ;) Generally speaking, 700 cc Ultra High Profile implants on someone who is 5'2" and 110 lbs is going to look VERY top heavy. In fact, I would not recommend it since 1- it is unlikely to fit your soft tissue envelope if you are starting with a B cup, and 2- it will likely put an undue amount of stress on your tissues. Without evaluating you I can only make general comments, but usually someone who is 21, has not had kids, (and has not had history of massive weight loss), has a somewhat tight breast envelope, and there is only so much that can fit at a given time. If the breast is then allowed to stretch around the larger size, at some time in the future, the implant can be changed out to a larger one since the envelope has been stretched so more can fit. During your consultation, your surgeon should have assessed your skin envelope, and breast dimensions, and informed you what sizes are likely to fit and likely to look good on your frame. The looks part is again subjective, so while your surgeon may disagree on what would be the most attractive, she/he should be able to listen to your goals and explain if they are achievable, reasonable, and/or recommended. Also, please know that 700 cc implants do not stay as high and tight as they look when they are first placed, so make sure your expectations line up with what you will face in reality just due to soft tissue mechanics and gravity, etc. If you feel you don't have a complete understanding of what to expect, or if the risks of large implants were not explained, please see your surgeon for another visit BEFORE surgery so that you are not disappointed. Also, make sure the surgeon is certified by the American Board of Plastic Surgery.
