Getting a little pervy are we..
Anyway, the only skirt I can think of(other than the code exotic job set o.o) that would match that would be the archangel one, unless your friend had access to some cash. Don't expect to be able to get one whenever you want though, as each piece, no matter what character tends to range at the ~60mil mark and up.
As for that other question.. I'm pretty sure you can't at the moment, but iunno.
