Just in time for Hallowe'en comes a new black and white collection from OPI.

We thought it quite weird at first until we played around with the new shades and decided they were quite glam.

The collection features Black Satin, a shimmery black, Black Onyx, a pure black, Midnight Blue Glitter, black with glittering sapphire pieces and Alpine Snow, a pure white polish great for french mincures as well.

You can mix and match to make cool two-tone looks but our fave was the Black Onyx covered with Midnight Blue Glitter. Super-mysterious and the perfect witch costume accessory!
