Ok, so here is what I learnt.. just to show I am actually interested in learning this stuff. OK so a blender node is used to blend two textures together and a transparency map is used to hide bits of one texture that you don't want to see. 

So as I understand it, with the transparency map I am hiding the skin parts of the texture so that what I do only effects the silk bit? 

Now I have seen how to make lips shiny but that effects the whole area. I just took the advice and I changed the node from the blender node and added a anistropic one, but again this has changed the color of the torso if you notice in the picture. 

Also if you see the marks just above the top of the lingerie?
