I have to say that I love it! It's not perfect: I need a better stand as it has a tendency to fall over, looking at it was initially very depressing and I've lost weight since I made it so its about a size too big. It is however extremely useful. UPDATE I did get a better stand!
I HATE doing fitting, especially FBAs. Doing it on yourself - like so... is really tiresome. And usually (when I did it anyway) inaccurate. Don't get me started on flat pattern alterations. They just bend my brain. And again... poor results (in my experience!).
PersonallyI find it SO MUCH EASIER to do this...
If you would like to see how I use it to fit bodices - have a look here.
