How Will DDD or E Cup Look Like After Breast Reduction to C Cup?

It may not be possible to go all the way down to a C cup if you are a DDD or an E cup now.   There are limitations based on the amount of tissue that must be preserved to maintain circulation and sensation to the nipple, and allow for healing of the skin.  It is best under these circumstances to tell your board certified plastic surgeon that you would like to get as close to a C cup as possible, and let them reshape your breast at the time of surgery to the size that is most appropriate based on your anatomy.  Then you will get the best breast shape that can be achieved, and maximize the chances of a risk free recovery!

You would have a life changing experience if you decrease and change the size of your breasts that much. If your breasts are that large, they are probably somewhat lower in position, so a breast reduction would lift the breast and make it perkier in appearance. It also can provide a very pleasing shape to the breast after surgery, again making it more youthful. Lastly, you will feel much better if you have back pain because your breasts won't weigh you down as much anymore! most women describe it as a complete life-changing experience and are extremely happy.

It may seem appealing to choose what your new cup size would be, but that's actually not how the surgery works. While it is very helpful to know what a person’s goal breast size might be, it is not possible to choose an exact cup size before surgery. Every bra from each company sizes their cups differently, and the cups also vary based on a person’s overall body size. The best approach is to provide your Doctor with a photo of your ideal breasts on someone who has a body similar to your own. She can then focus on shape, not size, and discuss a realistic outcome with you for what you're looking to achieve.
However, going from such a large size to a smaller size for yourself, would make a significant difference. You would have reduced neck and back pain, a more proportional look, increased confidence and self-esteem and a more youthful appearance. With smaller breasts also, women enjoy that their breasts are less droopy and their shape is much improved. So there are not only functional benefits but also aesthetic benefits from breast reduction surgery.
