This is ChG Skyscraper from the Fall 2011 collection whose name currently escapes me. Isn't she pretty? It reminds me of thousands of tiny little diamonds in the sky. I know for some folks, the lemming of Essie Starry Starry Night(s) is insatiable, however, this is plenty pretty enough for me...dupey or not.
This is one coat of Skyscraper over one coat of ChG Up All Night (a staple one-coater layering polish in my stash <3).
