Recently I bought Essence - Glisten up. I saw some swatches online of it on its own, but I didn't like it much, but after I saw it layered over some more darker colors, and I was sold. It's a polish that's pretty sheer on its own, a sheer blue with blue-ish green flakes, shimmers and glitter. = Succes for pure awesomeness.
I layered it over Models own - Pure Purple. Love. Love love love. Close-ups next to the text!
