Is 475cc Saline Enough to Give Me a D Cup?

I'm currently a 34B- would 475cc give me the D cup I desire?

475cc Saline Breast Implants to move from B to D cup

There is not a direct correlation between implant size and cup size as cup size is an inaccurate and often misleading measurement as there is great disparity among bra companies and even within the same company.

The size of the implants are based on a combination of a patient's goals and objectives and her anatomy. In order to provide a natural looking augmentation, the surgeon needs to evaluate many factors including soft tissue coverage, skin laxity, chest wall width, breast imprint width, the shape of the breasts and relative level of constriction to ensure that the breast implants are appropriate for your body. Consult in person with 3 experienced and expert board certified plastic surgeons to understand your options.

Is 475cc saline enough to give me a D cup?

 Hello! Thank you for your question. In general, implant size does not correlate with bra cup size. The cup size itself will vary from manufacturer to manufacturer as well as who is doing the actual measurements. Thus, cup size is never a reliable indicator for your breast size. I typically encourage my patients not to communicate her desires in cup size but more on the actual look and appearance.

Good communication between you and your surgeon of your expectations is warranted - choosing your surgeon wisely is the first step. Discussion of your wishes and having an honest and open dialog of your procedure is mandatory (e.g, implant type, incision, placement, lift, etc). I have found that photographs brought by the patient is helpful to get a visualization of the appearance you wish for in terms of size, shape, fullness, etc. In addition, your surgeon's pre and postoperative photographs should demonstrate a realistic goal for you. Once this has been accomplished, allow your surgeon to utilize his/her best medical judgment during the procedure to finesse the best possible result for you after preoperative biodimensional planning and fitting the right implant for your breast width.

Hope me that this helps! Best wishes for a wonderful result!

Implant Volume and Cup Size

Patients do quite a bit of research on the internet and often see me with an idea of what size implant they desire.  However, it is difficult for a patient to know the true dimensions of the internet patient's chest, their ribcage shape, chest circumference, and other factors important to know in predicting cup size.  

In general, about 200 cc is an average volume in what a thin woman with a 34 inch chest circumference would need to gain a cup size.  I would predict, that in your case, a 475 cc implant with a likely overfill will be more than enough to gain two cup sizes.  You may actually end up a bit larger!

There is no way to guarantee a particular bra size. Bra sizing varies greatly between bra manufacturers and a C in one bra will be a D in another. What matters more than the assigned bra size is the way the implant looks on you. The best option for your body and aesthetic goals can be determined in a thorough implant sizing session.

Implant sizing depends on several factors. One of the most important factors is your breast width. Generally, your surgeon will measure your breast width, and then provide you with a range of implant sizes appropriate for your native breast size. There are more nuances to it than just what I've described, but this approach works for most women.

I usually have my patients bring in a large bra and a tight t-shirt to do sizing. I'll then choose 3-4 implants that I feel are appropriate, and have my patients place them in the bra under the tight t-shirt. My patients can then look in the mirror and get a good sense of what they will look like with the provided implant sizes. My patients like this approach and get a great idea of how they will look.

By using this technique, your surgeon can outline a range of appropriate implant sizes that will be aesthetically pleasing, and you make the final decision.

I hope this helps. Good luck!

Implant Selection Process

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.

Guesstimating A Cup Size Is A Tricky Business


Usually, breast implants increasing the size of breasts from a B cup to a D cup requires should fall within the range of 500-525cc so your guesstimation of 475cc may work for you.

However, without a physical examination and trying out different implant sizes when in consultation with your surgeon I believe that you may not have a fair idea of how your breasts may look like after breast augmentation with a given implant size.

Moreover, patients with breasts asymmetry (even slight) should anticipate to have implants of slightly different sizes to achieve the best results possible.

That being said, please remember that commendable results require an exceptionally skilled surgeon to perform the surgery and settling for anything less than that increases the chances of additional corrective surgeries dramatically.

I hope this helps and please feel free to check the website below.

Thank you for your inquiry.
The best of luck to you.

Cup size is fashion dependent

Bra cup size is very fashion and manufacturer dependent.  I tell my patients that I can place them in 3 different cup sizes just by visiting different stores. In order to get the desired result from your breast augmentation, many board certifed plastic surgeons use an objective measuring system of your body that includes breast width and stretchiness of skin.  Some also have a sizing system to try on to simulate the desired result. Visit a board certified plastic surgeon to try them on and communicate openly with your surgeon about your desires. Good Luck.

That size implant will be near the range you have described


As you may have learned already cup size may be variable depending on the bra manufacturer and the size of the bra that the individual prefers to wear.  In general an average size woman will get a cup size increase with 225-250 cc implants.  I would encourage you to try on that range of implants in your plastic surgeons office and determine for yourself if that is the size of breast you would like to achieve regardless of "cup" size.

All the best,

Implant size

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. Even your fitness levels and other relevant criteria are taken into consideration. It is you who will decide what you are comfortable with.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.

Hope this helps. Dr. Basu Houston, TX

Cup size is not easily calculated

As has been noted, every bra manufacturer has different specifications so there are no hard and fast rules. You haven't provided a photo, height, weight, etc. Generally, the implant size you have noted would produce a two cup increase. Sizing is an art and I suggest that you see a board certified plastic surgeon in consultation (and reconsultation) to discuss implant options.
