I can't find the names of these formats in KYM or I'm not searching hard enough. The only posts I can find are "draw 25", "you have uno", and "uno reverse card", none of which describe the posts above.
It looks like this is the image those posts are parodying. I'm not sure if it's a named meme, though.
Showgirl Skirt might be what you're looking for, for skirts that are long in back and short in front.
I think showgirl skirt doesn't cover the front? it's more like a fabric trail.
update:I found it in tag group:attire, it's high-low skirt. It wasn't in tag group:dress, where I looked for, so I missed it. Went ahead and interlinked it to a few more places, hopefully that'll make it easier to find.
How to tag the girl with a beanie? I think there's another tag similar to motion lines. Does hat removed covers this kind of situation? And her eyes?
^^^ can be used for a crown. I'm not sure if hat launch ought to be used in conjunction with hat removed. Blank eyes is used for the missing eyes with solid shadeless sockets.
