Get Rosario Dawson's Bold Red Mouth
A red mouth can get a bit messy (because it's so intense, it's obvious when it smudges or gets on your teeth). But Rosario pulls it off beautifully.
To stop color from slipping outside the lines, draw a clear, waxy lip liner (like Too Faced Borderline, $18.50, sephora.com) around the outside edge of your lips, then apply a coat of red lipstick (try Make Up For Ever Rouge Artist Intense in Satin Raspberry Red, $19, sephora.com), blot, and apply a second coat. And to ensure that lipstick won't end up on your teeth, stick your finger in your mouth, wrap your lips around it, then pull your finger out—it'll wipe off any pigment that's on the inside of your lips.
