The polish is Sinful Colors - Starry Night, which I found in the new Halloween display at Walgreens. Amazingly, I walked away from the display with only this polish, but looking at the new limited edition glitters, it's definitely making me want to go back.
Starry Night is a black jelly with lots of multicolored glitter and some gold shards mixed in. I want to almost call it a galaxy in a bottle. I did galaxy nails once before, which you can view here. Since there was already so much glitter and dimension in my base, I used less polishes this time.
