Here's a couple of questions you might not KNOW the answers to, but could maybe speculate on?

How well would it work if you put your corset ON the form, tightened it down, and then fit the gown over top?

Since you can get extra covers, would it be worth tailoring the covers for different "lines?" One snugged in tight for the corsetted styles, one loosey-goosey for self-supported German, etc.

Umm.... where did you take an electric knife to it?
