I found a few discrepancies in my first set, mainly that the measurement for my shoulder length was only 3 1/4". I had used the 10cm measurement given by KK in his book. Also, I found out that if I relaxed my shoulders, my end of shoulder measurement was now almost 1" less, and my figure width was reduced by 3/4" as well. That'll bring the BPs up for sure!
I also figured out a better way to get my across back measurement. Rather than distorting my body while trying to hold one end of the tape measure at the start point, I wrapped the tape measure around my shoulders and back, read the starting number at the first measuring point, and the ending number, then calculated what my back width was.
Okay... so here's the NEW moulage sloper I drafted.
