Nude lips can be hard to pull off if you don't use the right shade. The key is to select a color with the slightest pink undertones, rather than brown or yellow undertones, which can make you look like a corpse. (Fun.)
It's always fun to pair a nude lip with a smoldering, smoky eye for evening, but for day, keeping the rest of the face clean with only a touch of pink blush is very flattering. Take a cue from this Rag and Bone look with Vincent Longo Wet Pearl Lipstick ($23) in Dahlila Flesh.
