What is the typical measurement range for determining if someone has a narrow chest? Is the original bra size an indicator?

Thank you for the question. There are no hard and fast rules when it comes to diameter of breast implant versus diameter of breast. In other words, these measurements are useful but are only one of the many factors come into play when it comes to selection of appropriate breast implant size/profile.

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. Again, have a full discussion and communication regarding your desired goals with your plastic surgeon. This communication will be critical in determining which operation and/or 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 who makes the bra; therefore, discussing desired cup size may also be inaccurate. Therefore, I ask that my patients not base their communication preoperatively OR their satisfaction with the outcome of surgery postoperatively, on achieving a specific cup size. The use of computer imaging may be very helpful during this communication phase.
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. The use of temporary intraoperative sizers, viewing the patient's breasts in the upright and supine position, are very helpful during the breast implant selection process.

I hope this, and the attached link (dedicated to breast augmentation surgery concerns), helps. Best wishes.

Thanks for your question.  In order to determine an appropriate range of implants for you, your surgeon will measure your breast dimensions and take into consideration other factors such as your breast tissue thickness, skin tone, and your overall proportions.  Of course, your desired size will also be an important consideration.
