Pulling my hair out on this one... some people that do foam versions use a tying corset style solution, but that is incorrect. This is how it should look like:
Some people have cheated and cut the sides open all the way across the "golden skirt", but you can see that the lower part is solid (although the upper golden trim is cut open). But, it doesn't look like the lower part is loose/separate either.
Any guidance? Keep looking at pictures but can't figure it out.
