Btw,
I brought up models to exemplify something many of us will never achieve. You'd like to achieve more fat distribution. As was mentioned before, it honestly may not be in your genetics, as a model physique is not in mine. Cliche is cliche, but women come in all shapes and sizes... my best friend is cis and has almost no hips, a straight waist, and her extra calories (if you will) does indeed accumulate in her belly. She's a beautiful woman, regardless!!!
Also, it's a fact that as we age, no matter what sex/gender/hormone-levels-in-the-body, fat starts to go to the belly more and more.
I really wish I could find a suitable answer for you though! If surgery isn't an option (body contouring can produce amazing results), a diet with more healthy fats and cardio exercise may help, or (probably not ideal) shape-wear that can go under clothes to enhance hips & booty.
