You might have seen here, I’m totally obsessed by my new cat eye sunglasses. I love the flick, I always love the flick, even the feline flick of eyeliner. Like red lipstick, cat eyes flicks owe their timeless appeal to their spectacular, style-defining range that can, depending on application, telegraph Old Hollywood glamour, graphic minimalism, or counter-culture punk – what else do Siouxsie Sioux and Brigitte Bardot have in common? It’s impossible to think of Marilyn Monroe without those heavy-lidded bedroom eyes or Amy Winehouse sans her subversive, exaggerated swipe. A mere sweep of eye pencil transformed Anna Karina from a fresh-faced teenager into a French New Wave style icon, and Sophia Loren’s wide-eyed gaze has been forever etched into our collective memory with a frame of perfectly delineated black powder liner.

Here’s a look at the best feline eyes of all time.
