Permanent Effects and Health
So we’re discusses how tight lacing won’t permanently change your shape in a matter of months -this is because it merely disperses the fat (moves it) and this will move back to its original location. Corset training can however have a permanent effect on your ribs, the lower ones in particular. This really does sound scarier than it is!
As it happens, your lower ribs are a fairly flexible set of bones as they’re attached at the back but the floating ones – as the name suggests – aren’t attached to anything at the front. So maintained pressure from a conical shaped corset will over time reshape them. Theres some debate over whether or not they eventually return to their normal shape if corset training is ceased completely, but as they’re bone this is unlikely unless there is a lot of internal pressure to push them back out. I don’t pretend to be a doctor so I can’t give you a ‘for sure’ answer.
As for the health issues associated with corset training, there is no substancial medical evidence to prove that even the extreme tight lacers of today like Cathie Jung, or those of the Victorian era,suffered negative health effects at the hands of the corsetier. A lot of the historic fatalities attributed to corsets were either laughable or can be put down to other health problems that the Victorians were unaware existed. I’m not saying you couldn’t crush yourself or do yourself a mischief if you tried hard enough, you can. And old or badly made corsets have been known to brake and cause steel bones to pierce the skin. But if your corset training responsibly you shouldn’t come to any harm. The internal organs are designed to be moved around to a degree in the woman’s body to accomodate a growing child, in fact they are put under similar or greater strain during a pregnancy.
