Funny you should mention that your size is 28DD...I am too. Well, technically I am a 26E...but they rarely make them.
As for how many cup sizes I increased, I really have no clue. I was wearing ill-fitting bras from the start, mostly 32B. They just sat on top of me, especially when I started getting bigger. If I had to guess, I probably would have been a large 28C when I began.
Obviously, I was really confused by my measurements initially, so I didn't set my goal in terms of cup size. I thought an inch and a half would be reachable, so that's what I went for. Now...honestly I think a 28FF or so would look great on me in relation to the rest of my body. I'm sure it sounds massive to a lot of people, but it really isn't. I am going for proportional here, I promise, boobie greed aside.

Slowly reducing pumping is definitely the way to go for maintaining and keeping it. I'm so glad I did.
It's true; I couldn't escape the boobie greed. I am under the impression that most of us rarely do. So, I'm back for more.
