It's Monochromatic Week on All Things Nails and my immediate thought was black & white, although monochrome means one colour or shades of one colour, so black or white, or any other colour. I checked it out on Wikipedia and that is the case but the term is often used to mean the same as black & white.
Anyway, that aside, I decided to do black and white and having just acquired Nubar Black Polka Dots I thought it would be a great opportunity to try out both the Black & the White Polka Dots.
I don't actually own a pure white, but I have OPI My Boyfriend Scales Walls which is a very pale grey, almost white, and I have used Nails Inc Black Taxi.
So this is my base...
