It's the Starlight Dress from RDNA. It's 2 pieces...a dress and a shawl. Each is one layer. You work the dress first, then the shawl. The only thing is that I'm not crazy about the way the shawl behaves once it gets to the bottom of the dress. It positions very well, but it's a long shawl and drags on the ground for quite a way. The shawl loses it's shimmery texture and takes on a flat hue of whatever colour you are rendering over, on the parts that aren't over the body or gown. You can see a bit of what I mean on the front of the skirt. I cropped it away from the bottom of the dress, because on the floor it looked like a patch of dingy grey that didn't belong. It seems it's because of the transparency. I'll have to play around with the settings for that. It comes with a really great tutorial on how to work with it too. You need a basic understanding of the cloth room as the bare basics aren't covered.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
