Rihanna's look for the inaugural event was focused on three things: her hair, yellow dress, and bold eyes. So looking past her hair and dress, if you long to get Rihanna's bold and beautiful eyes then begin with a great earth-toned eyeshadow palette such as Lancome Color Design Eyeshadow Quad in Showstopper Style (Compare Prices). Then line the your eyes, both top and bottom, as close to the lash line as possible with a good gel liner, such as MAC Fluidline Eye Liner (Compare Prices), and finish them off with two or three coats of mascara, such as Cover Girl Exact EyeLights Mascara (Compare Prices) in your matching shade.
To finish off Rihanna's look, apply a nice peach-toned blush to your cheeks and then finish off your lips with a natural looking pink lipstick such as Bobbi Brown's Creamy Lip Color in (New) Coral Pink (Manufacturer Site). If you want to add a little more depth and glamour to your pout then feel free to add a small dab of shimmery lip gloss in the center of your lips and then press lips together to distribute naturally.
