Is anyone familiar with this pants fitting system (for women) that was sold by the American Fashion Institute, Inc.?? The "magic-fit" pants kit. I foolishly bought the system way back when--late 80's, I think, and I have never been able to figure it out. It came in a colorful box, but when I looked inside, there were 2 ! complete pattern sets. You'd think I'd attempt my markings on one of them, knowing I had a spare just in case. Nope..just found it easier to keep on doing my old way of fitting to my own self. Does anybody have any hints or prods to get me to give it a try? I have some nice suiting to cut up.
