Firstly, I'm a trans male (FTM) and unfortunately I have a D cup. Top surgery is too expensive right now, but I plan on starting hormones soon. I'm looking for a few facts on the affects of hormones (T) on breasts if any. Do they cause any shrinkage at all or any other kind of side effects to breasts?

I agree with Dr. Greenwald, your D cup breasts will need surgery eventually to tailor the excess skin. Hormone therapy is not going to provide adequate skin reduction by itself.
Hormones for FtM SRS
Male hormones will suppress estrogen. This will lead to some decrease in breast volume but not to a decrease in breast skin. You can expect your breasts to droop as the volume decreases. To get from a D cup to a male chest contour you will need a formal surgical procedure at some point.
Testosterone may cause acne and hair development on your chest. If you develope hair it will likely be permanent, even if you stop the hormones.
