I made this up for my FA but thought it may be useful here as well :3

To be clear, the masking tape/duct tape is actually taped *OVER* the existing dummy (with garbage bags under it).
I keep the original dummy as is so I can fit the suit over it and do the final tailorings. Plus I have to adjust the covering when I apply it so it will fit like a piece of clothing and not like inflexible skin.
