Chanel_platinum_duo Metallic is fast taking over black and dark nails as the colour for finger nails, and yet again, Chanel have the colour everyone wants. Platinum Duo isn't just an ordinary metallic - the three layers of polish (one base, two top) actually create a sparkling, shimmering oh-gawd-I-have-to-have-it holographic effect. But unless you've already got a pair smugly sitting on your dressing table, getting one might be a little difficult. As like all Chanel must-haves, it's pretty much sold out.
