I have been forced to see something I didn't want to see. There is a significant number of people that think the bones in a corset are there to support the body. To this I say, no, the fabric is there to support you, the bones are there to support the fabric.
Oh, and corsets are not intrisically torture devices. I have worn some pretty comfy corsets. I have worn some not so comfy ones, too, but that goes for any piece of clothing that doesn't really fit.
