Black satin corset w/ruffled trim:  $4.95 $3.35 @ Ebay (seller gave me a partial refund since there was a hole in it)

I wasn't that impressed when I too it out of the package-putting it on was a different story!  It has an incredibly flattering fit-I like that the hooks are adjustable, so I can loosen it up in the bust area.  That makes all of the difference when you don't have much up top...
