I had the pleasure to review 12 of the 18 polishes in the newest OPI collection for Christmas 2014 called Gwen Stefani Holiday for OPI*. The collection was created with Gwen Stefani and contains colors from red to purple, green, silver and gold plus four glitter top coats and a golden flakie top coat. It will be available at the end of October 2014. As always, you can find more information about OPI on the OPI Swiss website or their Facebook page. I swatched every color with two coats without base or top coat and I will write a little note for each color this time. Overall I think it's a nice collection, but not too exciting. There are a few colors which stand out for me though: Cinnamon Sweet, Comet in the Sky, Sleigh Parking Only and First Class Desires. Pictures after the jump!
