Will 425cc moderate plus profile, mentor silicone give me the fullness and size I'm wanting? (Photo)

Unfortunately, you have not told us your bra size just your
cup size. If you are 32 or 34 each 100 cc’s of implant corresponds to 1 cup
size change.If you are 36 or 38 each
200 cc’s of implant corresponds to 1 cup size change.From this, you can compute the volume
required to achieve your desired goal.Your breasts are widely spaced, slightly low and have no upper pole
fullness.I recommend a new technique
called Breast Augmentation with Mini Ultimate Breast Lift™.Using only a circumareola incision it is possible
to reshape your breast tissue creating upper pole fullness, elevate them higher
on the chest wall and more medial to increase your cleavage.Aligning the areola, breast tissue and
implant over the bony prominence of the chest wall maximizes anterior projection
with a minimal size implant.Small round
textured silicone gel implants placed retro-pectoral look and feel more
natural, are more stable, less likely to ripple or have complications needing
revision.Implant profile is irrelevant
in the retro-pectoral position since the muscle compresses it.Best Wishes,Gary Horndeski, M.D.

Dear Denahs,    Thanks for submitting your picture. You appear to be a small A cup. You did not submit your chest circumference measurement, however since you say that you are broad shouldered, let's assume that you are 34 small A cup. To become 34 full C cup or 34 small D , you will need implants with volume of , roughly, 450cc to 500 cc. I would like you to reconsider your decision about gel implants. Saline implants are better option for the following reasons : 1. 1/3 of the cost. 2. Small incision under the areola as oppose to long incision in the submammary fold which is not scar friendly. 3. Sub areola entry allows for easier pocket's dissection and creation of nicer and more precise cleavage and submammary fold. 4. In case of a leak, saline implants replacement is simple while gel implants is complex. Always, consult with board certified plastic surgeons who operate in an accredited surgery center for your safety. Check the before and after pictures to make sure that they are numerous, consistent and you like them. Check also the reviews for positive patients experience.                           Best of luck,                                             Dr Widder

A few issues. Poorly posted photo, over internet we can only guess, confusing the concept of yours, "...on the edge of natural and obvious."? My over the internet guess is you desire a rather larger appearance, so I believe you need a larger implant - in the 450 to 500 cc range. But better you seek more IN PERSON opinions... 

Some surgeons recommended 300 ml, others 500 ml.  As you can see opinions will vary.  It's hard to give you a good idea, but I do leave you with the thought that I've never had a women say " I wish I went smaller" but on occasion one does say "I wish I went bigger".

It is impossible to size you properly without a formal exam in person. If you feel comfortable with your surgeon then discuss with him your goals. You can always do a baggy test to see if the volume is what you want.
