Our Corsets are sized by 'reduced waist size'. This means the size of the corset when fully closed. For example, a size 24" corset will measure 24" when fully closed. To determine your corset size you need to measure your waist firmly and deduct a number of inches.
Please note that your jean size is not your waist measurement! You need to measure the narrowest part of your torso which is a lot higher up. The amount of inches you take off will depend on a variety of factors, including the corset style and your build, but is generally between 3 and 5 inches (precise details are included for by corset style).
