Choosing a breast size for your body frame is a science and an art, which is why you should take care when you are choosing your plastic surgeon. Most plastic surgeons will provide you with a recommendation, but ultimately the decision will be up to you.
When considering the size of your implants there are several measurements that must be taken. You will need to consider the native base width of the breast. This will determine the maximum volume for each implant that you would be able to accommodate. For example, 100 cc differences could make a large difference in a woman with a narrow base width, but would make less of a difference in a woman who has a wider chest wall.
Some of the other critical decisions about the size will be determined by your plastic surgeon. He will look at whether or not the implants are going to be above or below your pectorals muscle.
When you visit your plastic surgeon it is a good idea to bring in some photographs of what you would prefer your breasts to look like. This can help provide your doctor with a reference point when it comes to choosing the right size of implant for your body type.
Most plastic surgeons will have some type of software morphing program that they can use in order to show you how a different sized implant will look. However, these programs while helpful in some cases, they may not be accurate in all cases.
The best thing that you can do when trying to determine the best breast size for your body type is to visit a plastic surgeon to have your measurements taken. You will want to discuss different options with your physician so that you will get the breasts that you want.
