Uhg, Black nail polish.

I hate it. Hate it.
Don’t get me wrong, there are people that can rock it, I’m sure.
But it just looks god awful on most people.
80% of the time, it’s not classy, and it’s not mysterious, it’s not sexy, it looks gross, emo-esque, and trashy.
You want a dark bad ass colour? Use a deep red or purple, even Gun Metal Silver would be great.

Or even any one of these!

Just not black. It’s awful.
