Anyone into corsets or waist training?

Any women out there into corsets or waist training? It's always something that has interested me, but I've been intrigued more lately. I'm interested mostly because I like the look and I've also heard it can be good back support, especially if you have back problems. I've always had a weirdly small waist, even when I've gained some weight, so maybe that's part of it. But anything that can reduce backaches, look sexy and provide support is a good thing.
