As others said, estrogen seems to really lie to keep as much fat in place, as it can. I am trying to loose 20 pounds for a while now, and I found it is way harder to do this than it was prior to tarting HRT. If you can start now with your loosing, it would be great.
Estrogen will not cause existing fat to move from the undesired places (belly and love handles with me) top the desired place (Breasts and butt), but just deposited new acquired fat there. You have o loose the fat at the places you don't want it, and than start to build up new fat n the desired areas.
