If any of y’all have access to a 3d printer or laser cutter & a 3d model of themselves and want to print out a 1:1 scale dress form, LuBan will do the trick for you nicely. It not only can split a model into sections for 3d printing but can hollow and peg it, as well. If you have access to a laser cutter, you can make one like this, which you can cover with fabric/etc… They have a Facebook page for it, as well, and the FB group is FULL of examples of what people have been using it for.
Hope this helps!
