Read this article on busks, which were one of the many devices used, mostly by women, to make their clothing stiff.
I realize this is a totally historically accurate thing, but when I read stuff like this it makes me want to throw up. I complain all the time about my jeans being tight; when I see women wore things like this I think "there's no way I could handle that."
There's mention in this article that one busk has a love message on it. It might make an interesting detail of a romance story.
