In my case, my band size changed. Before HRT I had some forms I would wear, and I bought bras to wear them with. I normally wore a 38, but I had even felt like maybe I needed a 40 at one point. 15 months into HRT, and my band size is 34 now. In my case, I think my band size changed more because of the t-blockers than the estrogen. I had a very high testosterone level, and tended to get a lot of muscle even when I wasn't exercising. I had huge amount of muscle around the upper part of my rib cage, right under my arms. T-blockers melted all of that muscle away, leaving me with a less triangular body shape and a smaller band size.
I think I gain more weight on HRT than I used to. I always used to have this magical ability to eat anything I wanted to, and gain zero weight from it. Now I have a bit of belly pudge. I do notice that I have more fat distribution now to my chest and my butt. My butt actually deflated for a little while when I started HRT (due to muscle loss), and then filled out more than before in fat. I don't notice much fat making its way to my hips, but I'm sure that due to my bigger butt, it kind of looks that way from behind.
I haven't gotten any shorter on HRT, and it's hard to tell if my shoe size has changed at all. I don't think it has, but for some reason I have found a few shoes one or two sizes smaller than my old norm that fit me alright now.
I'm 5' 9", and I don't personally see that as a passibility problem. There are tall women out there, and it's actually a very attractive trait to lots of people. My height means that I generally avoid anything with a heel and I have to alter most of my dresses to not be scandalous on me, but other than that I'm actually fine with it.
