The last Halloween Collection I'll show you for now is this one by Cadillacquer :) They are already available at Hypnotic Polish and color4nails.
(I'm wearing two coats with a glossy top coat on each swatch.)
Bones, a deep taupe with white hex glitter, black and orange micro square glitter.
Zombie, a green holo with holographic micro glitter.
Tell me what you think!
