If you have a warm skin tone that tans easily, or are of Hispanic descent, nude lips like Jennifer Lopez's will be most flattering.
Like tan skin tones, nude lips with peach undertones work best. Try Rimmel London Moisture Renew Lipstick in Nude Delight, $4.99, or, for a peach with subtle shimmer, Hourglass Femme Nude Lip Stylo in No. 5, $30.
Skin tones that sit somewhere between olive and dark -- like Halle Berry's flawless complexion -- look best in flesh tones with a hint of rose.
Halle Berry tends to favor barely-there shades like Revlon Colorburst in Créme Brulee, $7.49, and Chanel Rouge Coco Shine in Satisfaction, $35.
