Beyoncé's Makeup Artist Created Fall's It Eyeliner Trend

It's not the first time we've looked to Sir John for trend predictions. He brought us PB&J lips, a technique coined for mixing different shades of lip colors and smacking your lips together to create a personalized look. "The PB&J hack is actually one I stole from Beyoncé," he told us, "It's like you're walking around with a piece of art on your face."

This time around, just in time for crisp fall leaves and perfectly broken-in blue jeans, Sir John is back with a new makeup forecast: "denim" eyeliner. "I am obsessed with this look," he says. "It is one of my favorites. It's super on-trend for fall and anyone can wear it!" While cobalt blue has certainly made the rounds before, this time, the look he created on Joan Smalls is reminiscent of a denim-on-denim outfit with an intense, thick liner above and below her top and bottom lashes. Try one of the famed makeup artist's favorites, L'Oréal Paris Infallible Silkissime Eyeliner in Cobalt Blue ($9) or a go-to at Byrdie HQ like Rimmel's Scandaleyes Waterproof Kohl Kajal Liner in Deep Blue ($7)

Below, Sir John explains his favorite ways to make it work.
