Will I really look like this after 425cc? Will I be a 34D/32DD? (Photo)

No. Sizers in front of your breasts and in a bra is only an estimate or "a glimpse" of how you could look in the future. I think it is as close as a surgeon can get to show you how you're going to look without actually doing the surgery. Unfortunately, there's no completely accurate way to show what you're going to look like with the implants in place under your muscle. However, the vast majority of women who have breast implants are extremely happy despite these shortcomings.

I appreciate your question.

It depends on your chest wall measurements and existing breast tissue as implant size does not accurately correlate to a bra size.  It also depends on the brand and style of bra you wear as size varies from manufacturer to manufacturer.

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!

Trying on sizers is more accurate than 3D computer modelling but still are not exactly as you'll see after surgery. Often after the implants are put inside, especially under the muscle, they do look a little bit smaller than they did while sizing. Hope that helps! 

Thank you for the question.   There is no accurate/reliable/predictable correlation between size/profile breast implant utilized and cup size achieved. For example, I do not think that the generalizations of "200 cc equates to 1 cup" hold any validity or are helpful in any specific or practical way.  In my practice, I ask patients not to communicate their goals, or evaluate the outcome of the procedure performed, based on cup size references.Generally speaking, although useful as rough guidelines and as communication tools, all the modalities currently used to predict what breast implant size/profile will best achieve a patient's goals with breast augmentation are NOT very accurate, in my opinion. The use of the rice test, sizers placed beneath a patient's bra, goal pictures, computer imaging technology… are all useful, but not necessarily as accurate as one would hope.
In my opinion, nothing will replace careful verbal preoperative communication with your plastic surgeon, preferably in front of a full-length mirror along with the use of as many "communication" tools” listed above.
In my practice, I use all of the above modalities and then use intraoperative temporary sizers to help determine the best breast implant size/profile to achieve a patient's specific goals as closely as possible. For this reason, I think it is helpful to have the entire range of breast implant sizes/profiles available in the upper room.
Ultimately, careful communication of your goals (in my practice I prefer the use of goal pictures, direct examination/communication in front of a full-length mirror, in bra sizers, and computer imaging)  as well as careful measurements (dimensional planning) will be critical.
Generally speaking, the best online advice I can give to ladies who are considering breast augmentation surgery ( regarding breast implant size/profile selection) is:
1. Concentrate on choosing your plastic surgeon carefully. Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. Ask to see lots of examples of his/her work.
2. Have a full discussion and communication regarding your desired goals with your plastic surgeon. This communication will be critical in determining breast implant size/type/profile will most likely help achieve your goals. 
In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. For example, 
I have found that the use of words such as “natural” or "D/DD cup” etc 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. Again, the use of computer imaging has been very helpful during the communication process, in our practice.
3. Once you feel you have communicated your goals clearly, allow your plastic surgeon to use his/her years of experience/judgment to choose the breast implant size/profile that will best meet your goals. Again, in my practice, this decision is usually made during surgery, after the use of temporary intraoperative sizers.
I hope this (and the attached link, dedicated to breast augmentation surgery concerns) helps. Best wishes. 

Thank you for your inquiry. You will come close to the size in the photo but you may want to have a slightly larger implant to ensure the desired size you want to obtain. Good Luck!
