Asian girl, age 26. I want breast implants that look natural (photo)

Thank you for the question. There is no accurate correlation between size of breast implant and cup size achieved.
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're 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. I have found that the use of words such as  “natural” or "B or C 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.
 The use of computer imaging technology may also be very helpful during this communication process.
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.
I hope this (and the attached link, devoted to petite framed patients) help.

I have a fair number of Asian patients, and there are subtle differences to their treatment.I can definitely say, however, that I couldn't tell you exactly what style and size implant you would need to get your desired result without a consultation with you first.  Besides telling me exactly what you want, I need to do an examination and take a number of measurements in order to determine what will fit you properly.  We then have you try on a range of sizers to see what you are most comfortable with.In terms of breast augmentation in an Asian woman specifically.All the best !

Given that an exam, measurements, and your desires will be discussed at consultation. The Sientra textured highly cohesive gel implants that are shaped can give a look you desire.
