Have you ever watched "Rear Window"? If you haven't, be prepared to fall swiftly in love with the impeccably dressed, impeccably made-up Grace Kelly. One look at her regal mien, and it's not tough to understand how she became Princess of Monaco.

Kate Moss is famous for a lot of things (perhaps most notably, those cheekbones), but an on-point cat eye has long been part of her iconic modeling career.

If you're not familiar with Diana Ross and her popular '60s girl group The Supremes, just know that Beyonce basically played her in "Dreamgirls," and that tells you all you need to know. We all bow down to Queen Bey, but Diana was (if possible) even more fabulous.

To this day, Audrey Hepburn remains one of the most well-loved film stars ever -- and she's got a killer cat eye to match. Though her eyebrows were perhaps her most defining feature, her eyeliner was always flawless as well.

This one's a double whammy, since both Elizabeth Taylor and Cleopatra had legendary (literally, in Cleopatra's case) winged eyeliner. Add that to the epic blue eye shadow/kohl power duo used in "Cleopatra" the film, and you've got yourself a true look for the ages.
