The right nude lip can make you look fresh-faced and natural, while the wrong choice can make you look completely washed out. I would suggest that while picking a nude lip colour, choose one with peach or pink undertones. That way the colour will perk up you skin and will require very little makeup alongside. The YSL Baby Doll Kiss & Blush in 10 is by the the best looking nude that I have seen. Its not too brown or muddy, but has a pink undertone that lifts the complexion.
