I've seen pictures before of those "corset" piercings.
Those are surface piercings, only designed to be in place for a few hours, or maybe a day or two, at the most. The body will start rejecting them almost immediately. It is a combination of how they are done (shallow) and the type of skin they are placed in (ie, not cartilage, like you would find in a pierced ear). They look dramatic but are designed for short term decoration. Even so, you couldn't talk me into it, even for a few hours!
