After many hours of cussing, I finally have progress.
Here is the test run of the corset with the bustle. There is still a little to be done on the bustle (mainly adding a waist band), but it will have to wait. I need to get the skirts done and then evaluate how much bulk three waist bands is going to add at the waist
The plan for this weekend is to get the underskirt done with the box pleated trim added and maybe, just maybe, get the overskirt sewed.
