I think most of the credit goes to getting a quality haircut. I got a wolfcut with lots of layers and bangs. I show lots of refrence photos. It took a while to build up the courage to say i wanted a feminine cut and to find the right style. I’m pretty lazy with styling. I just use a round brush and spin it while brushing the sides back and bangs down.
Squats are good for thighs and butt. I do cardio, crunches, and push ups in addition to that. Cardio helps keep you slim and crunches are good for a flat stomach. Honestly I don’t spend as much time as I want on fitness. I want to do more calisthenics, cardio, and yoga. From what I’ve seen those seem to be helpful for developing a feminine physic.
