Although this corset uses plastic stays which denotes non-fetish level corsetry, it it built with a full 14 stays all the way around so you get the best possible shape with the lightest weight.  Laces in the proper corset manner, from the top down to the center and the bottom up to the center.  Then has hidden hook panel in the front, is fully lined in black, and has black satin piped trim all around.  Sizing is as follows:   Small is 24 inches completely closed.  Medium is 26 inches completely closed, Large is 28 inches completely closed, XL is 30 completely closed.  You never want to have it completely closed, so what you do is add an inch onto the size for a slow give of the fabric once it's exposed to your body heat, then you want to order 2-4 inches below your natural waist size.  The bustline will take care of itself.  Just remember to lift them up as you tighten in back for the proper support and for maximum effect.  Has a privacy panel in back so you will not be exposed in back, and that's how it is able to fit several waist sizes at once.
