One of the items up for grabs in my Giveaway is the Maxfactor Fantasy Fire nail polish, hotly sort after as a dupe for Clarins 230.
With a very similar colour and holographic turn to it Fantasy Fire is such a pretty duo-chrome shade that turns purple/blue/green/red depending on the light.
This is definitely a layering polish, either layered over other colours or layered up on its own for this amazing purple colour.
I have it layered over No7 Betty Blues here on the left (looking reddish gold) and bottom right (see the green flash?) and over OPI That's Berry Daring on the right, with an almost golden finish.
Only downfall is the size of the brush, tiny bottle equals tiny brush.
If you haven't been able to get your hands on one yet, click the Giveaway link at the top of the page where there's a chance to win one along with MAC's Viva Glam Nicki lipstick.
