I Am 5 Ft. 90lb Dr. Recommend 225cc Mentor Silicone, Under. Is This a Good Size for Me? (photo)

 As you can imagine, despite your good description of body type and goals, it is not possible to give you precise  advice online.
 The best online advice I can give to ladies ( in regards to best breast implant size/profile) who are considering revisionary breast augmentation surgery 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 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.



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) help.

Thanks for this question. Both sizes mentioned are within the ballpark to achieve a solid augmentation. The bigger you go, then the less likely it will look natural, specially with your small breasts. The final cup is better determined after  examination and seeing your natural shape. May I suggest you think about using a volume sizing system (VSS) will help you feel more comfortable deciding from your choices. Discuss this with your PS.  Best wishes, Dr. Aldo.

Hello.

Thank you for sharing your pre-op photos.

A difference of 25cc (225 or 250) is about table spoon and should not make a bold difference even on a small frame like yours.

With that perspective, the subpectoral implants advantages are many especially if you are after the "natural" look.

That being said, please remember that commendable results require an exceptionally skilled surgeon to perform the surgery and settling for anything less than that increases the chances of additional corrective surgeries dramatically.
I hope this helps and please feel free to check the website below.

Thank you for your inquiry.
The best of luck to you.
