I used a thin striper brush and OPI's Lincoln Park After Dark Matte to create some matte black French tips over OPI's Zom-Body to Love. Although Lincoln Park After Dark isn't a black it is so dark that it appears to be. It is actually a deep vampy purple. You can think of this as a simplified Frankenstein mani that has been popular the last few years.
I used my trusty eyeball to help with the contrast on the tips, you can see them a lot better in the photo below.
I think it's Halloween chic :)
