I Have Small 34B Breasts, Can I Go to 34D Breasts Without Looking Too Fake? (photo)

Thank you for your question. When a patient mentions natural looking, they are normally referring to the upper pole fullness of the breast after breast augmentation. There are two considerations with breast augmentation as far as implant selection goes. Shaped implants and lower profile implants will decrease the amount of upper pole fullness compared to the higher profile round implants. In addition, size will increase the entire breast, so a very large size will fill out the upper portion of the breast to a greater degree than a smaller size.
I would recommend visiting with a board certified plastic surgeon in your area to discuss your concerns in more detail and try some external sizers to get a feel and visual of what you will look like.

Breast implants naturally give more fullness to the upper pole of the breast.  A submuscular placement adds to this fullness.  There is no exact right number of cc’s to use since  every body is different and everyone’s desires and what they see is different.  Typically somewhere between 275 cc and 400 cc is needed to provide adequate shape and fullness, but this will vary depending upon the body type. Be sure to discuss your desires and possible outcomes with your surgeon. Implant sizers and looking at a 3 dimensional image of your body with implants often helps.

A great breast augmentation surgeon will be able to help you achieve larger breasts, without making them look incredibly fake. You should consult in person with a board certified plastic surgeon so he/she can examine you in person and then provide you with implant sizers to try on to get an idea of how different cc's will look on your frame. Together you can decided the best type of implant to give you the more natural looking results you want. 

Great question - what looks fake to you may be very different from what I think looks fake.  Best to try on implants in a bra - in the office  - and to use this metric to determine what you like best - and what you find most attractive...  Do not worry what I think looks fake - let's find a size that YOU find most attractive-  that is most important!  Best of luck.

You certainly can achieve a fairly natural but augmented look but will need to place the implants under the muscle to keep hints natural at that size as you are very slim in the upper chest
