I know you have seen this manicure before because it was my entry to Bundle Monster's Halloween Nail Art Contest. I didn't win *tears* but I had lots of fun doing it. Here are my good pictures of this manicure :D
I used Kleancolor Neon Yellow and Neon Purple as well as WnW Club Havana for the gradient; I topped it off with Covergirl Goddess. The plates I used were BM213, BM224 and BM225.
