If we wrote a book on classic makeup looks, it’s safe to say we would dedicate an entire chapter on how to create the perfect cat eye. As easy as it would make things, cat eye makeup is not one-size-fits-all, because everyone has different eye shapes. It’s so important to take your unique eye shape into consideration to achieve the most flattering end result, even if it takes some trial and error to get it just right. “Play around with various techniques to discover what complements your eye shape best,” says Nikki DeRoest, celebrity makeup artist and Ciele Cosmetics founder. “I would recommend dedicating some time to practicing the cat eye look and experimenting with different styles. I love playing with shapes in the morning before I shower, so I can practice and give myself space to mess up or experiment without ruining my makeup for the day if it doesn't work out,” she adds.To help you learn how to apply a cat eye for your eye shape (read: hooded eyes, upturned eyes, downturned eyes, monolids and more), keep reading for expert tips from DeRoest and makeup artists Elle Leary and Emily Oliver.
