Should I go for 365cc or 405cc implants?

hello thank you for your question and provided information as well;..based in your question its difficulted evaluate your case if the question dont have a picture, its recommended to get a consultation in personal with a plastic surgeon.

Depending on the individual anatomy and desired results, estimations and measurements should be made for each patient individually along. The elements that form up the breast shape and size and the overall frame can be different in each person. It is best to consult a board certified plastic surgeon who is experienced in cosmetic breast surgery in person and discuss your goals and options after a physical examination.Hope this helps,Ali Rıza Öreroğlu, MD FEBOPRASEuropean and Turkish Board Certified Aesthetic, Plastic and Reconstructive SurgeonIstanbul, Turkey

Patients often think in terms of cup size when considering augmentation. Unfortunately, devices are sized in terms of milliliters (cc) of volume. This can lead to some confusion when sizing. Additionally, it is important to remember that cup size itself is not standardized with variations from one manufacturer to another. Unfortunately, as many women can attest their cup size in an industry leader such as VS is not necessarily transferable to another brand.
Another point which is often under appreciated is that of anatomy and starting point. Any implant will add volume to the volume which is already present. The implant is additive. A particular volume will not necessarily confer the same cup size to different patients (often times it will not even confer the same cup size to different breasts in the same individual...remember they are "sisters" not "twins"). 
A general rule of thumb is that 125cc can represent somewhere between 1/2 to a full cup size increase. Smaller volume differentials (25-50cc) are typically less consequential representing a volume change of less than a shot glass. However, I have found these numbers, at least anecdotally, to be of little help. Patients often present with notions/goals which do not correlate with these sorts of sterile volumetric assessments.
When sizing patients, there are a number of useful tools including:
-3D imaging (has the added benefit of offering a volumetric analysis of the pre-operative breast)
-Breast sizers (rice bags)
-Goal photos
I also recommend that patients commit to a particular look rather than a cup size. Once a patient settles on a look that pleases them the overall cup size increase becomes less relevant.The key to obtaining a natural result is to stay within the parameters defined by your BWD. This will ensure that you avoid the dreaded "fake" look. 
With regards to your specific question, I would not struggle over 40 cc as this will make a subtle difference (slightly more than the volume of a shot glass). As long as you were approporiately sized, you are likely to be satisfied with either choice. That being said, I would favor more conservative sizing in a smaller individual. Small patients do not typically have large breasts
As always, discuss your concerns with a board certified plastic surgeon (ABPS).

Hello, it's difficult to provide detailed advice based on a description alone.  It sounds like your surgeon has done a proper assessment including breast measurements, so they will be able to take your anatomy into consideration when providing advice.

Hello and thank you for your question.  Congratulations on your upcoming procedure.  The
best advice you can receive is from an in-person consultation.  If you do not want to be too large, then opt for the smaller 365cc size.  The size, profile, and shape of the
implant is based on your desired breast size/shape, your chest wall
measurements, and soft tissue quality.  This decision should
be based on a detailed discussion with equal input from both you
and your surgeon. 
Best wishes and good luck.

Dear jodibilly,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

The PS you have selected will be able to guide you to the correct size implant for your measurements and desires.  Measurements of the chest wall and breast imprint width as well as knowledge of all breast implant sizes and profiles should make this process easy. 
Try on a profile bra with the sample silicone and gummy bear implants of various profiles under a tailored blouse, tight sweater, swimsuit, and other garments you typically wear so that you have the best idea of whether the garments fit as desired with the implant selected.  I would recommend that you go with the size that boosts your self-esteem, and fits your anatomy. Choosing an implant based on an aesthetic goal that exceeds your anatomic capacity may lead to complications and possibly revision.Remember that the implants will look a bit smaller, particularly in the submuscular position.  There is no rule here, but you may want to add about 10% to the size you select from the sizers.

Hi. It seems to me that 405 CC's will do and even going to 450 CC's. But all depends on many factors to be taken in account and that your PS should service you as a guide. Of course you have the last word.International Member of the American Society of Plastic and Reconstructive Surgeons (ASPS)

The best cosmetic result in any
particular breast augmentation patient depends on a variety of factors,
including: your individual anatomy, realistic expectations, a thorough
discussion with the plastic surgeon about the options, and an understanding of
the pros and cons of any particular implant choice. Proper sizing is not just
about the number of cc’s. The thickness of your tissue, breast dimensions which
include the width, height, and projection, as well as chest wall width all need
to be considered when choosing an implant. Trying on implant “sizers” of
various shapes and volumes while wearing a tight t-shirt, bra, or bathing sit
at a preoperative visit will help you and your surgeon choose the optimal
implant.
There are no manufacturers' standards for cup sizing in the bra industry. The
cups of a 34 D and a 38 D are significantly different. Cup size
varies from manufacturer to manufacturer and even within styles from any
particular manufacturer. There is no direct correlation between implant number
of cc's and cup size in any particular patient.
Keep in mind that following the advice from a surgeon on this or any other website
who proposes to tell you exactly what to do without examining you, physically
feeling the tissue, assessing your desired outcome, taking a full medical
history, and discussing the pros and cons of each operative procedure would not
be in your best interest. I would suggest that your plastic surgeon be
certified by the American Board of Plastic Surgery and ideally a member of the
American Society for Aesthetic Plastic Surgery (ASAPS) that you trust and are
comfortable with. You should discuss your concerns with that surgeon in person.

Thank you for the question and pictures.   A 40 cc difference in breast implant volume may create a significant difference in outcome,  depending mainly on the patient's specific anatomic starting point and personal goals.
My very general advice in this regard:  utilize breast implants only as big as necessary to "make you happy" long-term,  without having the most common regret ( "I wish I was bigger"). Again, generally speaking, smaller breast implants tend to "wear" better over the longer term.
My best advice: more communication.
It is definitely worth spending more time (prior to the date of surgery) with your plastic surgeon to discuss further.  As you know, it will be important for many reasons, that you feel comfortable that you and your plastic surgeon are on the "same page" prior to proceeding.
One question that might be helpful for you to consider: would you be more disappointed if you are slightly too big or slightly too small after the breast augmentation procedure?
 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. Sometimes, it is necessary to seek several consultations before you feel comfortable about your choice.
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. I have found that the use of words such as “natural” or "D or E cup” etc may mean different things to different people and therefore prove unhelpful.
Also, as you know, cup size varies depending on him who makes the bra; therefore, discussing desired cup size may also be inaccurate. Again, best not to discuss your goals and/or judge the outcome of the procedure performed based on achieving a specific cup size. The use of computer imaging may be very helpful during the communication process. The use of in bra sizers may also be helpful. In other words, use as many “visual aids” as possible during the communication process. I encourage patients to meet with me as my times as necessary, to feel comfortable that we are both on the “same page”.
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. I generally select appropriate breast implant size/profile after the use of temporary intraoperative sizers and viewing the patient's chest in the upright and supine positions.
  
I hope this helps. Best wishes for an outcome that you will be very pleased with.
