What are ways the ballerinas can loose stomach fat that won’t make them bulk?

I need to know some ways to loose some stomach fat and some leg mass. I am getting a ring right above my hips of extra fat. Also my thighs from all the swimming I do are very muscular. Now I am a ballerina so I can’t be doing excericises that are going to make me look like a soccer player. Excercises and food suggestions would be good. I need some help looking like a ballerina again.
