There is perhaps no more useful skill to have come Halloween night than the perfect cat eye—practically a required skill for those last-minute costume changes. The signature look is just as versatile as it is reliable, as showcased backstage from New York to Paris on the Spring 2018 runways. For an ultra sleek finish, along with a bottle that warrants a vanity spot, take on Guerlain’s liquid liner for a classic cat eye. Smudge out the ends for a more rocker chic style with Surrat’s dual ended liner or take on a softer, more feminine aesthetic with Clé de Peau’s delicate pencil liner. And for those who prefer a more dramatic finish, Shiseido’s Sumi Ink pot delivers bold pigment, while YSL’s 3-in-1 kajal liner offers a creamy, blendable finish. For whichever look you prefer, stock up on your favorite eyeliner just time for Halloween.
