I have no one willing or able to assist me in doing fittings for a corset I want to start. I intend to do a mock-up, but have only the assistance of a full-length mirror and my own two hands. The pattern I am using is Harlots and Angels Adventurer Corset, which is an underbust corset with a high back, wrap-around arm holes and a shortish busk in front. Is there a link someone can point me toward for self-fitting and measuring? There really is no one available to assist me: the last person I tried to work with actually made things harder and worse, not better, and there is no one else. She can't take direction at all.
