Hoopskirt for loli

[seeinglife.livejournal.com]

I'm taking a break from sewing and was browsing the fanplusfriend shop when I came across this petticoat that seems to have metal hoopskirt boning in it. Has anyone ever worn or made a pannier like this? I'm curious about what the shape is like compared to the usual cupcakey tulle creations, and how it is when you sit down. I know hoopskirts can be made that will collapse when you go through a doorway or sit, but I don't know how. Anyone here know?
