Why style prom dress would best suit my figure?

I am 5′7″ and have a pear shape figure, I have a small nipped in waist, wide hips, flat stomach and short quite thick legs, I have a long torso. Plus I have a small/medium size bust.

My best parts are my waist, and shoulders.

I am currently UK size 14, but am losing weight and will probably reach a UK size 10 or 12 by prom.

What kind of style dress should I be lookign for.
