34A wanting to be a natural looking and feeling B cup. Anatomical or smooth round? (Photos)

Thank you for the question. Based on your photographs, I think that you are starting at a good place and should have a very nice outcome with breast augmentation surgery.  Ultimately, careful communication of your goals (in my practice I prefer the use of goal pictures, direct examination/communication in front of a full-length mirror, and computer imaging) will be critical.  Personally, I think that for most patients considering breast augmentation surgery, careful selection of plastic surgeon and careful communication of goals, far outweigh the specific type of breast implant utilized (when it comes to the success of the breast augmentation procedure). Anatomical breast implants were designed to better simulate the natural breast shape; the problem with these implants is that if they shift or rotate, the entire breast will change shape as well. This change in breast shape may require further surgery to correct. Round implants, on the other hand, can shift or rotate without changing the shape of the breasts. ***Overall, I find that beautiful outcomes can be achieved with the use of round saline or silicone gel breast implants for the vast majority of patients.
 Generally speaking, the best online advice I can give to ladies who are considering breast augmentation surgery ( regarding breast implant size/profile selection) is:
1. Concentrate on choosing your plastic surgeon carefully. Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. Ask to see lots of examples of his/her work.
2. Have a full discussion and communication regarding your desired goals with your plastic surgeon. This communication will be critical in determining breast implant size/type/profile will most likely help achieve your goals. 
In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. For example, I have found that the use of know words such as “natural” or "B cup” etc means different things to different people and therefore prove unhelpful.
Also, as you know, cup size varies depending on him who makes the bra; therefore, discussing desired cup size may also be inaccurate. Again, the use of computer imaging has been very helpful during the communication process, in our practice.
3. Once you feel you have communicated your goals clearly, allow your plastic surgeon to use his/her years of experience/judgment to choose the breast implant size/profile that will best meet your goals. Again, in my practice, this decision is usually made during surgery, after the use of temporary intraoperative sizers.
I hope this (and the attached link, dedicated to breast augmentation surgery  for petite patients) helps. Best wishes for an outcome that you will be very pleased with. 

Thank you for your photos and questions. In general a round implant provides more upper breast fullness than an anatomic implant. The round implants are usually softer but there are some enhanced cohesive round implants that have been produced with a firmer gel like the anatomic implants. There are many other factors involved in breast implant selection so please see an experienced board certified plastic surgeon to select the implants that will best suit your goals.
