You Can Just Buy Things
Apparently, you can just buy anything.
Not a surprise really, but think back to the old days (for those of you old enough): where do stores get things like product racks and .. well, mannequins?
These days, its far easier. In my case, a combination of eBay and Amazon.

So I bought a mannequin from Ebay and a black body suit and gloves from Amazon. He definitely looks funny now but should start to take shape as armor pieces are added.
