5’2”, petite, barely an A, looking at 450cc HP to finally get an hourglass figure. Is this a big enough to get to D-DD? (Photo)

Based on your photo, and your description of yourself, 450 cc would not be an unreasonable implant size if you are trying to achieve a large breast size. What would be the ideal size for you can only be determined by actual examination and evaluation by your surgeon. Going from an A cup to a DD cup in a patient with limited tissue coverage can result in problems such as wrippling or wrinkling even with silicone implants

I appreciate your question
After performing hundreds of breast augmentations, I have found that the size of implant best for you is dictated by your chest wall measurements.  Once we determine that we can choose the profile based on what you want or need to achieve.  If you are seeking a natural look, then the diameter of the implant should be equal to or, more ideally, smaller than the width of your breast. The breast width is a measurement of how wide your breast is at the base, which should be measured at the level of the nipple. Choosing an implant that is smaller in diameter than your breast width will avoid the "side breast" fullness that is often associated with a more artificial appearance. Implants that are wider than this can be more palpable, fall more laterally overtime and also be more palpable. After that we will then choose the implant volume based on the measurements and also looking at any asymmetries you might have. You should choose a board certified plastic surgeon that you trust to help guide you in this decision. Bringing photos as well can help us to finalize, but please understand that these are of other peoples bodies and your results will probably be different.
Silicone will give you a fullness at the top (upper pole fullness). Silicone implants come pre-filled with a silicone gel and are the softest implant available. They feel more natural, which makes them a good option for women with less natural breast tissue; but they require a larger incision. It may be more difficult to realize if this type of implant has ruptured, so it is important to monitor them with annual follow-up visits. Additionally, because this implant contains a more softer silicone (less cross-linked), if this implant should rupture, it may leak but only into the scar capsule formed. However, the newer silicone in these implants may not leak even when the implant shell is ruptured. 
Anatomic gummy bear implants might be a good choice to give you a more natural look. These highly-sought-after, anatomic implants offer a look that more closely resembles the natural silhouette of a breast, and, therefore, are a very attractive option for individuals seeking a natural-looking, aesthetic primary breast augmentation. Additionally, these implants are an especially excellent option for patients undergoing restorative or corrective breast surgery because they provide more stability, shape, and reduced incidence of capsular contracture. Compared to other types of silicone gel implants, the silicone in the cohesive gel implant is more cross-linked; therefore, should the implant shell “rupture,” it maintains its shape and silicone does not leak.
 Implants, indifferent projections. The easiest way to think about it is they called me in a low medium and high projection or profile. Most of the time I use the medium profile which gives people the best in terms of natural look as well as a little bit of projection. High profile implants are for someone that wants  A little bit more of a fuller look. Low profile implants are better for someone that really wants a minimal extremely natural augmentation. Depending upon the anatomic versus round implants there are also subtle differences  in terms of the amount of projection for each profile. 
During your breast augmentation consultation, you should feel the different types of implants available, and try on various implant sizers in front of a mirror to help you to get an idea of how you will look following the surgery. You should also bring pictures of the look you would like to achieve, as well as a favorite top to wear when trying on implant sizers. I also use a 3D imaging system to allow you to try on a variety of shapes and sizes. I prefer this method over adding volume due to implants being under the muscle.
We will also discuss the possibility of needing a lift along with an implant. This will depend on the amount of ptosis (nipple position) as it relates to your breast, inframammary crease and chest wall. Needing a lift or not will also determine where to place the scar for the incision.  In some cases if the the breast and nipple is really ptotic (low) it might be best to stage the procedure by performing a lift first and then doing an implant at a second stage. This will also allow you to have a better understanding of the true size and shape of your breast.
In order to limit pain from breast augmentation and speed the recovery process I offer patients Botox into their muscles as well as a long acting numbing medication called exparel. 
The best way to assess and give true advice would be an in-person exam. Please see a board-certified plastic surgeon that specializes in aesthetic and restorative breast surgery.
best of luck!

Dear vintageglamgirl,Breast implant type and sizing selection is a complicated process and requires a detailed consultation that includes a discussion of your goals, a detailed examination, and a lengthy discussion. But the decision will always start and end with the patient. When it comes to sizing, we have all of our patients find 3 photos of their desired breast size. We ask for naked breast photos because clothing can obscure the true size (push up bras). Next, we consult with patients and go over the photos and take detailed breast measurements during a physical exam. Next, we using a sizing algorithm to determine a range of implants that will work based on the exam and the measurements.Lastly, during the operation, we use silicone sizers in the operating room to see how the size actually looks in the breast. We sit the patient up in the operating room, while asleep of course, and compare the sizer result with their desired look photos. If it is too small, we start the process over with a slightly larger implant. We don't stop until we get the perfect match.Of all of my breast augmentation patients, every one of them has been happy with their size due to this detailed and meticulous process. You don't want to invest time and money into a result that is either too big or too small.You should discuss your concerns with a board-certified plastic surgeon and make sure that your surgeon understands your goals.Daniel Barrett, MD

hello thank you for your question and provided information as well.. based in your question and the photos you must considerer about the cc , its recommended get a consultation with plastic surgeon to check how many cc do you need to get a very good results.

There is much to consider when selecting an implant.  Volume, style and projection need to be considered.  Your surgeon will help guide you through the process based on your surgical goals and your chest measurements.  Many surgeons have implants you can "try on" or other methods of helping you get a feel for how you may look after surgery.

You seem to be  a great candidate for breast augmentation an in-person consultation would be best for proper sizing. Always see a board certified PS.

Thank you for your question and photograph.  My advice regarding size selection is to spend time with your plastic surgeon trying on implants and view computer imaging if available.  Remember that a 200cc implant will increase your bra cup by approximately one bra cup size.  Best of luck.

You will almost certainly have an “augmented” look with those size implants, and it is unlikely to appear “natural”. If that is if little concern to you it is a personal decision and a matter of personal preference. We recommend using photos to communicate your desired look. Best of luck to you. 

Looking at your photos, it's not clear that it would be possible to fit a 450 cc implant in your petite frame and make it look good.  I would recommend basing the implant choices on the measurements of your soft tissue, rather than getting caught up in the numbers.  It's more about proportions.As the saying goes:  "you can't put 10 lbs of flour in a 5 lb bag".Best wishes,

vintageglamgirl. Please don’t get too caught up in numbers when it comes to choosing an implant that is right for you. I appreciate your desire to be as large as possible, however you must consider the fact that you are quite petite, and extremely large implants may not suit your body type.  
 I try to tailor each breast augmentation operation to my patient's desires and body type.    I ask my patients to bring in photos of breasts the size they desire, because there can otherwise be confusion because B or C cup can vary greatly by brassiere manufactures! I also utilize the implant in the bra technique, with several different implant sizes with a tighter fitting T-shirt to get an idea of what you will look like. Be sure to consult with a board certified plastic surgeon and go to your consult with all your questions written down so you don't forget to ask something.
