Due to a request I add a version of white ballet-tights, which should fit under the leotard and the ballet- or pointe-shoes. The mesh is simply a copy of the skin (except in foot region) of the base mesh. The texture is also based on an original skin with an additional white transparent and a white checker-board layer. When exporting to Blender, you may leave the Fresnel node or put the glossy/diffuse to a fixed value, e.g 30% of gloss. Adding displacement will make the structure visible, as you may see in the example picture. The complete character under the texture is made invisble by the delete vertex groups.
