My wife loves 'em... She's got a few true corsets and quite a few corset-like tops and lingerie tops. She talked a friend of hers into buying a corset, and a few days later the friend was telling all her female friends "buy a corset, it will change your life".
I have another friend who has CAD, and gets most of here custom made from a shop online called Blood Drop. She has some amazing corsets.
