I'm far more low maintenance on my nails than I used to be. Nudes in S/S, darks in A/W. Simple.
Essie's Luxedo is probably my all time pick for this time of year. A rich plum tone that could be mistaken for black in some lights, it's a little less intense than the real thing but still gives that touch of class and sophistication. I've been wearing my nails fairly short and squared off recently too; a far cry from the talons of the past but far more comfortable and easy to maintain.
