If you are not familiar, hormone replacement therapy happens in stages too, not unlike the rest of your Mtf transition. Of course, your change will depend on upon dosage and levels of testosterone already in your body. Always remember, estrogen will only take you so far, then has the potential to be very toxic.
Finally, my hips began to fill out as I saw for the first time yesterday. I could see what could/would have been, had I been born a cis woman.
You also need to remember with me, my advanced age (68) and the amount of time (6 months) I spent off HRT when I had the liver/iron problems. Add in the six months I spent initially on a bare minimum estrogen dosage and I feel I have been on serious HRT for three and half years.
I have always read, one must be on HRT approximately three years for hip development to occur.
At any rate, my quick glimpse yesterday was at once exciting and sad. Exciting on how far I have come and sad it took me so long to get here.
I know there are many who would argue that their cross dressing experiences are not flat and two-dimensional. They might say that their feminine self is nothing more than an extension of their three-dimensional male self. I understand it because, well, "been there, done that." As for myself, I had reached a point where even that was making me feel flat - no matter what gender I was showing myself to be. Even when I was living 80% as my feminine self, I was really no better than 50/50, because I had to be ready to make the change, either way, sometimes at a moment's notice. I felt like I was in a limbo, and I was not a good example of a woman or a man. Yes, I was cheating myself of a full, three-dimensional life, but, worse than that, I was cheating family and friends of my full self and the attention they deserved. Showing myself in a selfie, or, more to the point, as a selfie, was selfish and disingenuous. That is not what I ever want to be again.
Maybe, someday, I will reach a fifth dimension - about the time of the dawning of the age of Aquarius? (dating myself once again) :-)"
