You might have to have a series of a couple of them- in gradually smaller sizes and differing shapes- if you want to do this with the least potential for problems. The biggest problem of "sudden corsetry" is having the gut- stomach, upper and low intestines, bladder, spleen, liver- all crammed into a space that is too small for comfort and effective processing of food and nutrient in the body. Some women have a rib or two removed from the bottom of the torso to accentuate the smaller waist. Some will use a "gentle" corset for sleeping, and a more strict corset during the day. Ab and lateral rotational exercises, with moderate dieting with higher protein and somewhat reduced carbs, and a gentle to moderate corset would be the safest way to go to achieve a more tapered look. If you proceed, please do so under the care of a medical doctor.
