Can 340cc HP Breast Implants Result to D Cup?

Sizing needs to be done at the office, but w/o seeing you, I am skeptical 340cc will be large enough.

On another note, I stopped doing periareolar lifts years ago for a variety of reasons. If not willing to do a standard mastopexy, then consider a lollipop lift, and why textured as opposed to smooth wall?

It is very important to communicate your size goals with your surgeon.  In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. I have found that the use of words such as “natural” or “C cup” or "fake looking" 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 press 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.
By the way, the most common regret after this operation, is “I wish I was bigger”.
I hope this helps.

Very hard to say what a size will do for your individual breasts, but high profile implants combined with a lift will give significant breast projection. A 340 cc implant is a moderate size for a combined lift though a peri-areolar lift sounds like a great option may not be for significant breast sagging, and it has a tendency to flatten the breast. The scars may spread as well. Be careful with this procedure as it is commonly over-used, though rarely delivers the result it sounds you desire.
