Black Dahlia nails

That's what i came up with today. You basically need:

-a black nail polish. Get a highly pigmented, non-streaky one. I used Rimmel's 60 seconds in 800 Black Out.

-a clear nail polish. I used H&M in Clear (yep!). Preferably a thinner one that's also cheap so easier to part ways with.

-GLITTER! Purchased my tiny bottle from a Christmas fair several years ago, from a brand called Fairy Dust (never heard of it before); i use it occasionally for New Year's party makeup or such moments. I actually have three little bottles, pink, violet and blue. For this one i used the blue glitter.

Fairy Dust face&body glitter (for wet-based usage)

The glitter shines in a multitude of shades-baby blue, silver and purple- iridescent lights that will go wonderfully with a clear base.

Really simple- mix your glitter with the clear nail polish. Shake, shake, shake well and that's done. Do your nails with the black polish (or a dark purple, burgundy, whatever you wish- the darker the better, for a more dramatic effect).

 That's my result with the H&M clear polish. It looks either blue or lavender/purple, depending on the lighting.

Let it dry for about 10 minutes then clean up any potentially messy edges with a cotton bud soaked in polish remover.
Apply your clear (now glittery!) polish, veeery carefully so you won't budge the layer underneath and end up with an unidentifiable color.
Done! (my black nails are still a tad messy)
