I agree - it's different for every one and your results might not be anywhere the same.
As it is, I can only speak anecdotally - but I have opted to not go all the way and am happy the way I am. Still on estrogen in the form of Progynova, I originally started with Premarin which really hit me pretty hard.
In just a few weeks I had substantial breast growth, but emotionally I was a wreck. I cried at Three Stooges movies and couldn't even watch anything that normally would not cause me to tear-up and cry. Thankfully, this treatment (for migraines) lasted only six months - but by then I was wearing a pair of Bs and had a serious case of chest jiggles.
Fast forward to more recently and I am on Progynova - NO emotional highs/lows and I can even watch movies with sad themes without much crying at all. I "mist-up", but the crying jags are not there any more.
Fat redistribution wasn't so obvious on Premarin, but I didn't stay with it for longer than my EENT suggested for my migraines - which is why I took it in the first place. BTW: In spite of others' anecdotal stories, the migraines ceased almost immediately and have never returned after that treatment - go figger!
Today on Progynova for a substantial amount of time, I have good fat distribution, breast growth and especially they have filled in underneath to give great volume and shape. I have some nice cleavage and have gone to an almost D now, as "my cup runnith over" a little in Cs.
Weight gain was typical for anyone going over-the-hill, and I guess that although I am in no way fat or chunky, I can see a little tummy bulge now. As soon as I can get some pixs, I'll post a few of me here.
Hips, of course will not widen after male-pattern puberty has happened, as the bones get "fixed" into position and won't bend or grow in a new pattern. I imagine there is a surgical repair or modification available, but I haven't heard of it.
