There are a lot of beauty tricks that we'd love to learn from Adele [1] — like where she finds the perfect rosy lipstick, or the techniques she uses to sculpt her cheekbones to perfection [2] — but her signature cat eye is at the top of our must-know list. Celebrity makeup artist Lisa Eldridge [3] tracked down the colleague who created Adele's famous retro-chic beauty style, Michael Ashton, and enlisted him to create a DIY [4] on her YouTube channel [5].

Utilizing a close doppelgänger for a model [6], Ashton breaks down every step of Adele's now-iconic look and even divulges which products he uses to achieve them. Of course we're thrilled to finally learn exactly how he crafts that razor-sharp cat eye! Watch the above video to discover his tricks, then grab Bobbi Brown Longwear Gel Eyeliner in Black Ink [7] ($26) so you can practice re-creating it yourself.
