there's this stuff called "Powernet"... Joanns calls it Power mesh...the stuff I sell at the store I work at (aka not Joann's) a stiff somewhat sheer fabric that you could overlay, it should come in white as well as black and nude, I know for sure that it's pretty opaque even though you can see through it.
