Thank you for your email. A 250-300 cc breast implant should look fine on you. However be aware that even under the muscle Saline breast implants will likely show visible folds especially along the side of the breasts. I am sure that is why your surgeon is recommending Silicone Gel Implants, a recommendation I agree with.

There are different ways to establish the preferred volume for breast augmentation. Based on the photograph I think that a 300 mL implant would be suitable choice. You need to take time to figure out precisely what size you want to be

At size 32 each 100 cc's of implant corresponds to 1 cup size change.  A 300 cc implant will take you up 3 cup sizes to a C or possibly a D.  However, from your photographs your breasts appear too low.  If you implants are centered under your areola they will extrude underneath the pectoralis major muscle and you will need revisions.  I recommend a new technique called Breast Augmentation with Mini Ultimate Breast Lift.  Using only a circumareola incision it is possible to place the implant, reshape your breast tissue to increase upper pole fullness and elevate your breast higher and more medial to increase your cleavage.  Aligning the areola, breast tisuse and implant over the bony prominence of the chest wall will achieve maximum anterior projection with a minimal size implant.  The profile of the implant is irrelevant when placed subpectorally because the muscle will compress it.  I believe if you place a 300 cc implant through an inframammary incision your implants will bottom out and you will need a revision in a short period of time.
