Please excuse the state of my hands- I'm left handed so pens/pencils tend to rub off on my pinky finger. Anyway, this actually isn't a polish you can buy (although I'm sure you can find dupes for it!)
This combination is Sinful Colors Black On Black along with an extremely extremely old Maybelline Colorama Top Coat (21). The result of the top coat on the black polish is gorgeous. It makes this manicure look like a sort of galaxy. I'm obsessed. I can't wait to try the top coat over other polishes.
