Old-school Hollywood glamour is back!

The retro '50s eye makeup look is having a major moment thanks to a little show called "Mad Men." This seductive look is a classic that will never go out of style and continues to endure on the red carpet.

The most defining feature of the '50s eye-look is the wing-tip liner which expands slightly past the lash line for a subtle dose of drama that can be played up or toned down. Wear it with a bold red lip for a glam evening look or with a fresh face for a more natural, understatedly sexy style-- versatility is the reason this look will never go out of style!
