Small Frame with Silicone High Profile 275cc, 280cc, 300cc?

   For an average sized woman, 200 cc may be one cup size.  For a smaller woman, this is probably closer to 150 cc per cup size.  Thus, two cup sizes would be 300 cc.  So you are probably in the right range.  Trying sizers in the office is probably the best approach.  Find a plastic surgeon who performs hundreds of breast augmentations each year.  Then look at the plastic surgeon's website before and after photo galleries to get a sense of who can deliver the results.  Kenneth Hughes, MD Los Angeles, CA

I think 250-325 is the right ballpark for what you are seeking. The exact profile might be either moderate plus or high, depending upon your dimensions and goals. Discuss your goals with your surgeon. Often, sizers will be used at the time of surgery which helps with the final determination. Go for it.

As other have stated, personal examination is critical, as each of us may make our measurements of your breast anatomy slightly differently, but have made our surgical decision-making in line with out own particular way of assessing things. Experience plays a role here, as ABPS-certified plastic surgeons who have years of experience doing well over 100 breast augmentations per year have a high degree of expertise, and will usually have a better track record than even a well-trained colleague who only does a few dozen breast augmentations a year.

One thing that has only been obliquely addressed in some of the answers is the choice of profile. Smaller implants in the size range you are considering will have a narrow, high projection (as others have said, 15cc = one tablespoon, an undetectable difference--so let's just assume 300cc implants are the "perfect" size for you).

Mentor smooth round silicone 300cc implants (HIGH PROFILE) have a diameter of 11.1cm, which is pretty narrow. Allergan Natrelle smooth round silicone 300cc HIGH PROFILE implants are even narrower (10.9cm). Slightly smaller implants will be narrower still!  If you have a wider breast base dimension than is appropriate for these implants, you will have an unnaturally wide and unattractive cleavage and a "fake" Baywatch coconut look; perhaps moderate plus profile implants may be a better choice.

You are petite, however, so this may indeed be the profile for you. The point I am trying to make is that you do not choose size and profile based on surgeon's "preference" or "habit" or even that you might have "heard" that HP  implants look this way or that--you should choose desired size first, and if that fits your anatomy, then profile is selected to "fit" your breast base dimension so you don't end up with wide gaping "Grand Canyon" cleavage!

This is, of course, why you should select ABPS-certified plastic surgeons who do lots of breast surgery! For more information, click on the web reference link below for my Comprehensive Guide to Breast Augmentation. Best wishes! Dr. Tholen
