Add thickness to clothes after exporting from MD without adding unnecessary geometry?

I don't know if that's possible, since the sheets of fabric used in MD are pretty much 1 sided planes, you have to add the geometry to it because there is nothing there >_<
to kinda lessen the blow and not use solidify on the whole outfit, I would just put parts that require an inside , for example a skirt on it's own layer in MD
Then seperate that in blender and then either make a inverted dupe of the skirt or soidify just that.
