Thinner lips can look gorgeous and dramatic in darker shades—think Louise Brooks or Marlene Dietrich. The important thing to remember is that the texture you choose should stay a little on the creamier side. Matte shades are always chic, but because they're so dry they can “shrink' thin lips further. At the drugstore, Revlon Super Lustrous Creme Lipstick in Spicy Cinnamon is a classic. You could also take a look at Le Métier de Beauté Hydra-Creme Lipstick in Breathless, Illamasqua Lipstick in Magnetism (if you want something super pigmented), or MAC Lipstick in Spice It Up.
