/3/ - 3DCG

I'm trying to make a dress where the inside is a different color from the outside, but I can't figure out how to do it without the inside part of the dress clipping through the outside part of the dress in some way. What I'm doing is duplicating the part of the dress that needs the color and scaling it down so it'll sit inside the mesh, but this isn't working. It there a way to just make the mesh double sided? I tried using the solidify modifier, but I get the same problem with it poking through itself from different angles. I'm using Blender.
