I've been wanting to invest in a corset for the longest time but still can't decide on a style for my first purchase: overbust or underbust.

I think that I'd get the most use out of an underbust corset if I could just come up with ideas on what to wear with it so that I don't look like I'm on my way to a Renaissance Faire.

What do you wear underneath your underbust corset? To dress it up? Dress it down?

For that matter, what do you do on your top half to change up the look of an overbust corset besides adding a jacket/blazer of some sort and jewelry?
