You need to have taken the "Draft a Basic Bodice Block" class to take this one.
Learn to manipulate a basic bodice block made in a previous class using your own measurements. You'll draft the pattern, make a "mock-up"/"toile", try it on and have it fit by the teacher, Carol Miller (she's been drafting and fitting corsets for a few decades so you're getting of to great start). You'll make the alterations to the "mock-up"/"Toile" and adjust the pattern to reflect the alterations, ending up with an 18th Century Corset pattern that fits you. Think "Elizabeth in Pirates of the Caribbean"!
