Eyeliner. Notice how there's a hint of blue on her lower lids...and she has blue eyes. Traditionally you go opposite in eye makeup colors (blue eyes get neutral colors, brown gets jewel tones), but I have blue eyes and do this on occasion. It really makes them pop!
So I seriously love black hair... I wish I had it... I would rock an affro all the time... every time I see a girl with afro hair I am so jealous!!! Seriously!!!
