I sculpted Marilyn live in front of an audience. She is over 110 lbs of chocolate and painted with edible airbrush colors. The armature in the legs is 1 inch steel that attaches to a piece of wood at the waist. Then there is a piece of PVC that goes from the waist to the shoulders that attaches to wood spanning the shoulders. I researched by watching lots of video footage and studying still images. She took about 20 hours to sculpt.
