Lead makeup artist Kabuki, who used MAC products to create the metallic effect at Posen's show, played off of the designer's classic Hollywood aesthetic and blended a custom hue to complement each model's eye shape and skin tone. "There are slight nuances to each look, but the overall effect is about fluidity and glamour," he tells us. "We're almost proving that many different people can wear it---it's just about how you tweak the line."
Kabuki advises drawing the strike above either a black or brown base to avoid washing out the eye. You can find your perfect metallic by using your jewelry as a starting point; While cool-toned complexions, like the model above, are flattered by silver hues, the warmer your skin, the more gold you can incorporate.
At Carolina Herrera, makeup artist Diane Kendal extended the sparkle onto models' lashes by painting a mixture of silver glitter and Duo Adhesive ($10; maccosmetics.com) on the tips of fluttery sets of falsies. "The idea is to mimic the look of water droplets," she tells us.
If faux lashes aren't your forte, you can easily mirror the effect by adding a silver glitter mascara over your traditional formula---just be sure to concentrate the sparkle on the very tips to keep the look more modern than middle school. Kendal kept the lids bare, save for a few swipes of MAC Clear Lipglass ($15; maccosmetics.com), which can be substituted with lip balm for a less-sticky counterpart off the runway.
