tightlacing. Just wearing a Victorian style corset won't alter your bones atall. Plus, the whalebone they used for structure in those was waaaaay more flexible that any modern substitute. Most of the "OMG CORSET BAD!" propaganda is just that - propaganda, spread by ultra-religious "reformers" of the same stripe as the abolitionists. Ever worn a corset? Not a costume piece with shitty plastic "boning," I mean one made for everyday, with spiral steel. They're really not so terrible.
