Load the figure and zero pose. Load the cloth and parent to the figures's hip. Load the dias and position. Move the figure so as to be correctly positioned relative to the dias. The cloth will position with it because of the parenting. Advance a suitable number of frames. For simple poses I usually use 30. Pose the figure ignoring what happens to the cloth. Now into the cloth room. Don't select the "from zero" option. I usually add ten or so frames to the simulation to allow the cloth to settle after the figure has attained its pose.
