Breast Implants - 400cc Too Big for Small D?

I recently had breast augmentation and asked the PS for small D full C. I am 5'2, 105lbs and I was given 400cc. I feel like this amount was too big too achieve this look as I started off with a 32C. I have many friends who are taller than me and wider than me and they were given the same amount or even less to go from an A cup to a D cup. I have not D&F yet but thinking in the end I am probably going to be more like a DD or E. Am I being anxious or am I calculating this whole cc's thing wrong?

Wait to drop and fluff

Bra size is an inaccurate way to measure breast size. Bra cups aren't standardized and so a D by one brand could actually be a C or E in another. It's very unreliable. Therefore, what your surgeon thought was a D, as you requested, could have been true to them. I would suggest you wait until you've actually dropped and fluffed first then consider whether you got the results you wanted.

Also, it's best not to ask what your friends have gotten because their body type is different from yours.

Implant CC and cup size

It is very difficult to say whether or not a 400cc implant is too big for your frame without conducting a physical exam.  The appearance of a 400cc implant is highly dependent upon the patient's body frame, weight, height and amount of breast tissue that they currently have and it is important to note that a specific volume or cc will look very different on two patients, even on sisters of a similar body type!  Since it will take roughly 3-6 months to see where your implants settle out and for most of the post-operative swelling to dissipate, I would recommend waiting until you have reached this benchmark to make any final conclusions about size.  In the interim, I would also recommend following up with your operating surgeon to discuss your expectations and goals, as the surgeon might better put your mind at ease during this waiting game.  I hope this helps and best of luck!

Cc's and cup size

Dear Miami4877,

It appears that you are very early in the post op period.  Please, keep in mind that there is swelling that needs to subside and the implants will drop over the next 3-4 months to give you a smaller more natural breasts and look.

400cc implants look different in different people. Considering that you started off a 32C, it is likely very difficult to impossible to keep you a C cup or even a small D. Based on your examination there is a certain volume which best fits your body. Given that you are 5'2" and 105, 400ccs seems a bit large, but I can not tell you for sure as pre-op measurements, photos and exam are all essential in determining the range of implants that would have best fit you. 

Cup size is a ratio of breast volume to chest circumference it is tough to estimate exact post-operative bra sizes. Another confounding factor is that there is no standardization of this ratio by bra manufacturers.
However, a loose rule of thumb is that it takes about 150-200cc to make a change in cup size in a 34 circumference chest. Therefore if you are already a 34C, adding 400 will likely increase you a bit more than 2 cup sizes, likely (but not for sure) making you a DD or even more depending of how full of an C you were to begin with. If you buy 36 size bras you will find that the cup size would be smaller, so you may be 36C or D. Keep in mind, this is a very rough estimate and the goal should be the look and not a bra size. 

My best advise is that you discuss your concerns with your plastic surgeon candidly. Best wishes. 

Breast implant size

The look of 400cc implants depends on your frame, height, body weight, and amount of soft tissue. I would suggest waiting for your post-operative swelling to decrease and for your implants to drop before drawing any final conclusions about sizing. This can take up to six months. Be sure to have a dialogue with your surgeon about your goals and expectations. Best of luck.

D Cup after breast implants

I avoid using cup size when discussing breast augmenbtation results with patients. I ude biodimensional planning to give them a rangle of sizes that will look natural and ideal for their body type. Before and after photos can be an excellent way to communicate what you are look for from surgery.

Breast implants

400 cc implants will look differently on different people.  It is hard to say what the final size will be until the swelling comes down.  If you ultimately are unhappy with the volume, you should discuss it with yoru surgeon.

Choosing the Best Implant Size

The lettered cup system is not exact and varies among bra brands.  To achieve your goal breast size, the surgeon must gauge your starting size, the amount of breast tissue present, the amount of anticipated breast expansion, your breast dimensions, and your specific goals to name some.  During the preoperative evaluation, you and the surgeon go over different size implants and determine what is the best approximate size for you.  Different size implants are available during the operation and the one chosen is based on intraoperative sizing.  Temporary sizers are placed and filled to different volumes to see what is the best size. Once this is determined, the temporary sizer is removed and the permanent implant is placed.  So, choosing the correct implant is part science, part art, and part experience.

Wait for at least 6 months for an accurate evaluation.

You’re in the initial recovery stage of your breast augmentation. Your breasts are swollen and have yet to drop into position. It can take up to 6 months for postoperative swelling to subside and for your implants to settle into place, so it’s important to wait to evaluate if you’re satisfied with your final breast size. It’s not uncommon to feel a little anxious immediately following breast augmentation, as you’ve likely anticipated this procedure for awhile and are eager for the final results to reveal themselves. As far as comparing your procedure with your friends, each person is different. Height, frame, body weight and available breast tissue are all factors that affect final size. Be patient with your healing process and follow-up with your surgeon if you have any questions or concerns.


There are many variables in recommending implant size/type. I base my implant recommendation on patients' body (chest height, chest width, existing breast tissue) as well as their desired look. I usually do not talk about cup size. As you know, cup size varies with brand and styles of bra. I would go for the desired look. Review before and after photos and see what kind of look that you want.
Implants come in different types (silicone, saline), shape (round, anatomic), and profiles and volume. As you increase the profile of implant, you will get a larger implant.
More meaningful recommendation can be made based on direct examination and in-person consultation.
Please visit with a board-certified plastic surgeon.
Best regards.

Depends on pre-surgery measurements

Implant size and the resulting cup size really depends on your pre-surgery measurements, such as your breast width and height. That's why your implants may look different on you.
