Try on clothes, try on clothes, try on clothes.
You NEED to be that b*tch hogging the dressing room with your "6 at a time" and a friend outside with 106 more. You'll develop an eye for what works for you.
As a guess - fitted tops that cinch under the bust but release to the hip. I bet if you got a long enough blouse you could pull off leggings, you young thing you... Trousers with a wide leg - use your narrower bottom to "balance" your top. Create some hips and butt, and the tum will cease to take center stage.
Dresses?
You're gorgeous. Go thee hence and ownerize it!
(We edit a**? But it's such a great word.)
