Harness size refining Serre Sewing ...?

I started getting into sewing. I love cosplay and I'm looking a model that fits the requirements above. Of course, I expect to pay for it and did not need to be exact, but I'm still too new for the change could end very badly. I'm going for a steampunk feel, and I'm not afraid to put some hard work in ... but I can not find a model. I was disappointed (but not exactly a surprise) that the simplicity and McCalls had nothing, Butterick has a fitted waist, but that is not under control and it is thicker than I would have. I went through a few online stores, and while I found the corsets underbust belt hitched themselves, it seems that nobody has a model for them! If someone could point me in the right direction I would appreciate it.

ummm try to use the word corset underbust chinche belt harness is a brace http://www.elizabethancostume.net/custompat/index.html here is a site that you put in your measurements and it is the model for free
