Try bidding on ebay for one. Of course, when you type in your search, make sure to put in the tight-lace waist measurement you would like. for instance, search for "underbust corset 26" or "custom corset" i have found you can get a fabulous corset much cheaper than buying straight from the websites, like vollers, etc. Two really good corset sites are
