Personally I was there to find out more about ease, as it turned out it was just reading through the booklet, extremely brief, with no further explanation.
Guidance in accurately taking the body measurements was not satisfactory either, since some of us were unfamiliar with that. Placing the tape measure slightly higher or lower would give your a complete different reading, again no guidance unless you asked.
The public can get such information on internet, By doing a workshop you expect to get a more thorough explanation from the teacher.
I got nothing out of the workshop, I left feeling I wasted my time.
