Even with all of the skirts we have the devs are incredibly stingy about giving us many that are knee length, purely leg gear, don't have a odd waist-band, and dyeable. Everything usually seems to either be floor-length or it sits slightly below the crotch. Like, all that I can think of that meets all of that criteria is the crafted versions of the world of darkness gear and the far eastern beauty skirt.

The variety of leg gear and the length of body gear really need consideration.
