Will I wish I had chosen a larger implant size? The next size silicone implant was WAY too big but these are too small. (photo)

Since you haven't had surgery, you haven't "chosen" your implants yet. Unless, of course, your surgeon has to order the size you choose ahead of time. Plus, is your surgeon accommodating submuscular compression by adding about 10- 15% to your chosen size when sizing? If you liked the look of 505cc, I would use around 575cc implants in the operating room. If your surgeon implants the same size whose "look" you liked in the sizing room (505cc), you WILL be disappointed (too small). After 27 years and thousands of BA patients, how do you think I know this fact?In our office we maintain an extensive inventory of both saline and cohesive silicone implants in all sizes and profiles, so we never have to "order a few" in advance of your surgery. That way our patients can decide right up to the day of surgery--a few even re-size on the day of surgery! And if one doesn't look "right" after I insert it, I will have the proper one right there on-site, and would not hesitate to change it. Most surgeons use the choose-it and use-it or you buy another pair of implants and a re-do operation later!Also, you should understand that the next implant size up from your 505cc sizer is probably around 550cc (depending on implant manufacturer and profile required by your anatomy). That is a barely-visible increase--45cc is only 3 tablespoons! Your doctor's sizer choices may not have been complete--implants don't come in small, medium, and large; they have 30cc increments on the smaller implant end of the scale, 40-50cc increments in the midrange sizes, and 100cc (less than 3 1/2 ounces) increments at the largest sizes. We have a complete set of sizers as well, making choosing the exact size that is right for you much more easy than just having a few sizers or resorting to rice bags.Bottom line here--you need to re-size and decide what you want. Ask about adding a bit to compensate for submuscular compression, and make sure the profile chosen is the maximum width to best fit your pocket--otherwise you end up with HP implants that leave wide cleavage and less upper pole fullness (once they drop). Or get a few more consultations so you are comfortable with the process.

There should not be a tremendous issue of difference between
adjacent implant sizes.That being said,
if you ask 100 women one year after breast augmentation surgery, did they like
the size they chose, did they wish they went smaller, did they wish they had
gone larger, more than 50% will say they wish they want bigger.Just so that you keep in my mind.That being said, 505 cc implants are
certainly sizable.Best of luck.

It really is difficult for anyone online to give you sound advice without examining you and knowing your measurements. Just with your height I would think you are going large as it is and I personally would probably advice against going bigger but without speaking with you in person this is just general advice. The sizers that are over 450cc are flatter than the implant your surgeon may use if he/she goes with a high profile implant so hopefully you trust your doctor and discuss your concerns with them. good luck
