This is a sort of funny question, but (in the current scheme of things) where does a finished corset go? Obviously a finished bra would go in Bra Making, but "Hooray this is my newest piece" doesn't really belong in either Corset Patterns, Pattern Drafting & Fitting or in Corset Construction, Fabrics, Tools & Materials.
This is actually also a problem for girdles and mid-century shapewear as well.
I propose for the mid-century stuff that it could go in with bra making (Bras and Girdles, perhaps?) because a lot of the techniques and materials will be the same (moreso than corsets, it seems to me - stretch and synthetic fabrics will probably be a lot more common).
I'm a little stumped about corsets, though. I really like having the two fairly specific categories for making (patterning/fitting versus skills/materials), and finished work doesn't really fit in to either. On the other hand, I really don't want to add yet another board, especially one so very specialized. I guess if I had to pick, I would add it to construction: Corset Construction, Materials, Tools, & Finished Work.
