Blake Lively, and scores of other women, know that nothing says sun goddess more than gilded glamour on your lids. The more shades you have, the more depth you can create to this look, but really you just need a light, almost yellow, gold shimmery shadow (or highlighting powder) and a warmer, almost brown, gold shadow (preferably in a cream formula). Start with the darker, warmer shadow and apply that to the base of the eye lid, stopping right at the crease -- I adore Laura Mercier Caviar Eye Stick in Rose Gold ($24 at sephora.com) for this effect. Then use the lighter, cooler shadow and apply that at the crease of the lid and blend it in with the lower lid -- bareMinerals Eyecolor in Queen Phyllis ($14 at sephora.com) does the trick nicely. Lastly use an eyeliner brush to apply the lighter shadow right at the corner of the eye and along the lower lash line, creating a glowing rim around your eyes. If you feel the need you can finish this look off with a thin black line of eyeliner or, my favorite, just some mascara.
Also, if you like to have some variance in your shades, consider using something like Bobbi Brown's Shimmer Brick Compact ($42 at sephora.com) it features varying shades of perfectly shimmery shadows. It might be known as a cheek bronzer, but your eyes will glow and shine under its effects, too!
