No confusion! How did you decide to do it? Enquiring minds want to know!
If I were doing a project like that, I can think of several ways to make it work. The simplest might be a double-layer corset, with the casings on the inner layer and the embroidery on the outer. Benefit to that would be that you could use any fabric you liked on the outer layer, which would make embroidery a lot easier.
If you have the pattern pretty well planned out before you start, you could begin with the fabric flat and the pattern traced on, embroider all the big areas (allowing for seams and bone casings, then put it together and just fill in the blanks.
