So my mother was going to help me make one with duct tape, t-shirt and saran wrap per instructions on this site, but she decided to splurge and by a dress form so she could use it too.
I still may end up doing the duct tape dummy and put it over the dummy and pad it to make custom fits if I ever get really serious, but most of the things I am planning on "refashioning" are minor tweaks and I don't look too different than the model. But who knows if I will get to it now that I have one; I have other things to do!
I thought I would share so you can do it. Tell me if you do, looks like fun!
