Final Thoughts:

You get what you pay for! If you just want a simple cheap fashion corset without any waist reduction, OR if you’re looking for a cheap corset just take apart in order to learn how to recreate a corset pattern, then the cheaper corset may suit your purposes. However the Leatherotics brand offers custom sizing – this will give you as much or as little curve as you like. But remember the limits of each brand – if you want to be sure you get a corset made exactly to all of your measurements and specifications, you will have to go with an independent corsetier(e).
