Ok, can I even put this on here, I hope so. Just three of the many pictures I posted in my blog post for comparing the UD palettes. Hope they give you a good idea what are the difference. My number 1 choice is Naked palette for obvious reason. For the other four, Deluxe is my top favorite.
The Naked is exactly half width but double length of Deluxe palette.
Comparison not in ratio. Just to show you how they differ inside.
Detailed comparison of each of the palette. Including the price.
