A nude lipstick should look like your lips, only better. Here is how to find yours.
Look at your undertone
Veins that look green suggest a warm undertone; blue suggests cool. Warm undertones suit caramel and chai shades; cool undertones suit rosy browns.
Swatch on your lips, not your hand
The back of the hand is lighter than your lips. Swatch on the lower lip in daylight.
Line first
A liner one shade deeper keeps a nude from looking flat.
