How did they sit?!

Sometime in the future, when I get all of my sewing things set up, I would like to make some costumes from time periods that had...well...odd fashions. Things like crinolines or bustles or wide hoop skirts. Once I've got some of those made, I'd like to dress up in them for the whole day and see what it was like. It seems nearly impossible to do things wearing corsets or bustles or any of the other things that they used to wear, so I'd like to see if it's easier than it seems.
