Is it possible to have your natural waist of 10-12 inches smaller than your bust and hips?

Is it possible to have your natural waist of 10-12 inches smaller than your bust and hips? (Diet and exercise as natural numbers, but no surgery), because this model called Daphne Joy (shes all hot hip hop videos) has a great curvy figure slim, but its size in proportion to her hips and bust seems rather low, as shes been wearing a brace for years. Is it normal to have this form?

What do you call the skirts with the flap in the upper half gives the illusion of hips?

Anyone know what I mean? I tried googling, but couldnt find them. They are common in skirts but they flap like a piece of matierial around the upper half the width that gives extra width so that those with smaller hips can wear a skirt and look like they have hips?? Links would be very helpful, cheers
