Is 375cc too small for someone who is petite?

Thanks for your question. There are many ways that surgeons help their patients in picking the size of their implants. It is important that you pick a board certified Plastic Surgeon and review their before and after pictures. In my practice, I have found that having patients try on implants in a tight surgical bra has been very helpful. It is also important to review the different implant profile choices and the type of look you want with your surgeon. As a petite patient, you may need a higher profile implant to achieve the volume you desire without having the implant too far laterally (too much side boob).  It is important to have an honest conversation with your surgeon before surgery to make sure you get the results you are looking for after surgery. Best of luck!

Thank you for the question.  
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. Sometimes, it is necessary to seek several consultations before you feel comfort will about your choice.
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 "C or D 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, best not to discuss your goals and/or judge the outcome of the procedure performed based on achieving a specific cup size.
 
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 generally select appropriate breast implant size/profile after the use of temporary intraoperative sizers and viewing the patient's chest in the upright and supine positions.
I hope this, and the attached link (dedicated to breast augmentation for petite patients) helps. Best wishes.
