There are opposite lip trends battling it out right now. In one corner, there's the bold purple look being seen on the red carpets. On the other, there's the nude lip that Kylie's made famous.

Surprisingly, it's the barely-there option that's harder to get right. Still, you don't need to be Sophia Loren to go nude. You just need to choose a shade that works with your skin tone, instead of making it appear washed out -- or, you know, like you just caked your lips in concealer.

Makeup guru Bobbi Brown says the trick is finding a shade that looks like "an enhanced version of your natural lip color." According to Brown, it's "not necessarily the color nude, but a shade that is one shade lighter or one shade deeper than your natural lip color."

We rounded up our favorite nude lipsticks for every skin tone, keeping in mind Brown's advice that "the right nude will in turn complement your complexion -- it enhances the skin tone, makes the eyes look brighter, and gives the face a lift."

People with milky complexions similar to Jessica Chastain's tend to be of English or Irish descent and have light blonde or red hair and light eyes -- you also probably head straight for the palest shade of foundation at the makeup counter, and the strongest SPF at the beach.

Nude lipsticks with pink undertones that make the skin appear warmer -- like CoverGirl LipPerfection Lip Color in Crème, $4.99, or Bobbi Brown Lip Color in Blondie Pink, $25 -- look best.

If you have darker hair and eyes, but you still have a pale skin tone like Emmy Rossum, you fall under the fair skin tone category.

Like porcelain tones, you should still look for a pinkish hue, but a softer undertone like L'Oréal Paris Colour Riche Lipcolour in Fairest Nude, $8.95, or Lipstick Queen Velvet Rope Lipstick in Star System, $50.
