When I was little, I used to draw my mom’s red lipstick in a straight line down my mouth à la Padme in The Phantom Menace. In sum: I was a very ~cool~ child. Nowadays, I always want to pull off a vibrant, two-tone lip, but I’m not sure exactly how. Which color goes where? Should I use matte lipstick? A lip pencil? Clearly, I have questions. So I went to our good friend and professional makeup artist Shannon O’Brien for some tips and tricks. Here, she shows you how to get the two-tone lip of your dreams — with minimal effort and maximum effect.
