What Cup Size Will I Be If I'm a Size 34b and Get 390cc? I Am 5'4 and Weigh 115

It's a great question, but it's really hard to predict your final cup size. A rough estimate would be that every 150-200cc of implant volume would increase your bra size by about 1 cup. During your consultation you'll be able to try on implants in a bra. It's important to remember that cup sizes vary significantly between different bra manufacturers, so focus on reaching your goal look and then you'll find out your cup size during a bra fitting. When considering breast augmentation make sure you find a board certified plastic surgeon who will take the time to answer all of your questions and explain all of your options, so that you can decide if breast augmentation is right for you.

There is no formula to determine a predicted cup size after breast augmentation. The factors that figure into this are many including: 1 breast tissue to start with; 2 height and size of pstient 3 compliance of chest wall 4 shape of chest wall 4 manufacturer of bra.  This last factor demonstrates that bras are not even really standardized. Generally speaking, consulting with an experienced, board certified plastic surgeon will be your best plan to give you a reasonable indication of what postoperative bra size you can achieve. But no one will be able to guarantee any specific result or size. 

You are likely to be at least a D cup.  However, it is very easy to be confused by this measuring system. Cup sizes are only used as estimates for clothing. Although the measuring technique for determining cup size is precise, the results of these measurements are not. Let me give you an example; weight is a very accurate measurement. However two patients that weigh 120 lbs are not likely to look alike. The same is true with two patients that have C cup breasts. This is why physicians tend to use volume (cubic centimeters or cc) as a more accurate measurement. Note: If you are trying to figure out what breast implant size you want to obtain, you can try the szing tool available through b4bra.com or read the articles about measuring there.

Size is a complex decision that is not only based upon your height, weight and current cup/bra size but ALSO on also on your breast diameter, waist, shoulder, and skin envelope measurements. These can only be assessed in person during a consultation. A good place to start is using my "Find your perfect size" tool listed in the left hand column of my bodysculptor.com home page. Another good place to look is the searchable database section of the physicians' photos on implantinfo.com. Best of luck.

Hi there-

If there is one thing I would like to be able to immediately convince every woman interested in breast enhancement of, it is that the best implant for you should NOT be based on your desired bra size, or the number of cc's your friend has, or the way they look outside of your body in your bra...

Please understand that to achieve a pleasing long term outcome the implant needs to be chosen based on your body dimensions, your current breast parameters, your desired appearance (not bra size), and your lifestyle.

You can read more about this here:

One can only guess at the size following implant placement.  Most plastic surgeons can come pretty close to determining the correct size.  The difficulty is that all bra manufacturers are a little different.  You know this already if you have shopped at different stores and found that you were a "B" at Target, but a "C" at Victoria Secret.  In this case, I would guess that you will be in the full "C" or small "D" range.  Good Luck!

In order to make an accurate size recommendation, I would need to assess your chest wall and breast mound measurements and characteristics.  Unfortunately, there is not a general rule of thumb or objective criteria to implant selection.
Your plastic surgeon will perform several measurements of your chest wall and breast anatomy and determine a range of implants that both fit your chest wall and reach your desired goals.
The next step is to try on this range of implants in the office with your doctor.   The key to this success is showing your surgeon the body proportion you desire with a bra sizer and allowing your surgeon to guide you to the right implant.   It will be much easier to communicate in implant cc's than cup size when determining the appropriate implant for you.
I wish you a safe recovery and fantastic result.

It is very difficult to predict cup size because cup sizes vary by designer.  Cup sizes are not standardized.  I consider two factors when selecting implants for my patients:

1.Dimensional planning

2.Gel Implant Sizing system

Dimensional planning – The measurements of your chest wall are taken. Also, the breast dimensions including the height, width, and current dimensions of each breast form the basis of dimensional planning. Based on these measurements, the implant size is recommended. This will give you a unique breast implant that is suited for your body frame. However, there are some limitations of what size we can recommend. For instance, some implants may just be too big for a narrow chest wall. Your surgeon can review this with you during the consultation.

Gel Implant Sizing system – During the preliminary breast implant consultation, you will be provided with an option to “try on” a variety of implant shapes and sizes. You can also visualize the possible outcomes of your surgery which helps you to get that perfect size to give you the shape that you longed for. This way your preferences are known and you can then pick a range of implants that will “fit” just right to give a soft natural fuller look.  If you have decided on saline implants, then based on the gel sizer you select, we can guide you to the saline implant that achieves a similar look.

Hope this helps.

Just based on your height and weight, I think 390cc implant will give you at least D cup size.  Please remember that cup size varies depending on the brand of bra that you buy.  Usually, I ask my patients to bring pictures/photos of their desired look rather than concentrating on cup sizes.  Pick the right implant size will vary on your chest anatomy as well as your desired goal.

For each person the cup size increase is dependent on multiple factors, including the implant chest shape and width of the breast as well as the chest.  Even with a lot of experience it is not possible to predict accurately the exact cup size.

In your case you would be larger probable a large C or a D cup.

Shaky,

With your small frame, B cup breasts and that size implant you can expect at least a D cup result.  I've kept it simple here.  If you need more explanation see my website or the many answers below.  Good luck!
