I'm trying to make the armor from Dragon Warrior #1. I started with the "chest" at the bottom, and am almost done with the chest, but the problem is that the armor actually dips down to below the crotch area and i can't seem to move up the armor to build down. I can move up the model, but not the armor. Advice?

Skipping the cloak for now, no clue what so ever how to even begin making a cloak.
Going to try to make the sheath, but not sure if it will go far enough "down" to be able to make it part of the torso slot.
