How do you lose belly fat but not waist size?

Hello! I am wondering – my bust/waist/hip measurements are in line with what I want, but I want to lose the fat below where I measure my waist. I know spot training is impossible, but how is it possible to lose belly fat and keep your curves? Currently, I’m eating well and doing aerobic workouts.

How do i get really skinny really fast?

Bust: 35.5/6
waist :27
hips : 35.5/6

i am 5′4" and weight app. 114/5lbs
sorry no photo

I would like to be really thin so that i can pursue modeling.
