Celebrity hairstylist Bryce Scarlett, who also works with stars like Natalie Portman, Gigi Hadid, Brie Larson, and Emma Stone, used Moroccanoil products to perfect the style, which is one of the best examples we've seen of the A-line hair-cutting technique that's spiking in popularity among celebrities right now. The choppy ends are shorter in the back and angled to be longer toward the face, for cool, subtle movement that doesn't need a ton of fussy styling to look chic. Just add in some bendy waves and luminous, rosy makeup courtesy of Robbie's go-to makeup artist, Pati Dubroff, who used all things Chanel on the Oscar nominee, and you've got a winning look on your hands.
