Mesh in SL makes layering a bit frustrating especially when a lot of items are not modifiable leading to tons of weird intersecting if any of the articles overlap. Fortunately mixing the "painted on" with the mesh does the trick perfectly as does slowly collecting clothing items that were made to go together like this hat & hair.
