Have any woman used a waist clincher or corset and seen results?

I've been thinking about purchasing a hourglass waist corset but am very cautious because I've read online a few people didn't see results. So basically my question if you use these have you seen results and if so how long did it take to see them. I have fairly big breasts, booty and my waist is smaller than my hips but I want it to be noticeably smaller than them. So any help is greatly appreciated.
Thank you
