Disclaimer: I am chunky lazy bitch but have read a fair amount on this subject. So take the following advice with a hefty pinch of salt.
That totally depends on what you consider a more feminine body shape. But basic principles are:
1: fat is burned relatively uniformly according to how it's distributed. So you can't burn fat from your belly without also burning it from your hips.
2: the only way to change the bone structure of your pelvis/hips is to take enough estrogen and progesterone to simulate pregnancy. Don't do this without constant medical supervision or at all if you take estrogen orally. You don't need to actually have a baby to stroke out.
3: The one area that you can control is muscle distribution. So if you find exercises that build muscle on the quads and all three glutes you'll be fine. (Assuming you mean TnA)
4: Exercise releases HGH which will slightly increase breast growth.
So run, walk, cycle to the point of exhaustion every day, cut your calories a bit but not too much. Every other day do strength training and muscle building in the quads, glutes, and pectorals. This should give you a decent start. Once you're down to the lower side of a healthy BMI start adding back calories and see where they go. If you are lucky they'll go to your ass and thighs (the genetic lottery jackpot). If not concentrate on building muscle in your lower half.
For strength training you want to gradually increase the weight/resistance to the point of not being able to do 5 reps and then keep it there until you can. Strength training is about increasing motor neuron innervation in the existing muscle fibres.
For muscle mass, you want to go to your 1 rep limit every time. This damages the muscles and causes them to grow back larger.
