The hourglass waist cinchers will fit almost like a full underbust on those who are “short waisted”: those who torso length of 6.5 inches to 8.5 inches (at the princess seam).
It can also be worn by anyone with a longer waist who want to maximize mobility when wearing a corset, and those who like the look of a wide belt overtop of their clothing.
Those who have a protruding or low-hanging tummy may want to avoid this style.
