Best pattern drafting books/corset theory?
I am wanting to make custom corsets. I am relatively competent patternmaker and stitcher and work professionally in sewing. I have been looking for books that instruct about how to draft a corset pattern and explanations about why each thing is done. Have borrowed a book that is full of historical corsets and patterns but doesn't really explain how to draft custom fitted ones. Ie if I am starting from a custom fit lingerie block - where do I go from there?
Looking for great books or tutorials on this!
I would like to start off with an underbust corset but I have a friend that would like to make an overbust one with cups.
