Every season, Paris Fashion Week is a time for celebrities to experiment with fashion and deliver their boldest front-row outfits—and the same could be said for their beauty looks. This week alone, Katy Perry has embraced the wet-hair look at Balenciaga and Gigi Hadid the micro-bob at Vetements. But earlier today, Jennie Kim won for the most dramatic hair transformation of PFW: The singer emerged at the Chanel show and unveiled an ice new blonde dye job.

Forget going darker for fall: Jennie rebuked old-school beauty rules and marched to the beat of her own drum, choosing a perfectly-toned platinum shade instead. “Ready for a surprise?” she wrote on her Instagram stories, just moments before she made the big reveal. We certainly were: It was a head-turning change from her signature dark locks, though it felt entirely fresh.

The pin-straight, middle-parted hair look felt very Barbie—as did her look for the show, a sky-blue sweater with teal knit briefs, complete with strands of Chanel pearls around her neck. Don’t forget the quilted Chanel top-handle bag either—a VIP must if you’re sitting in the front row. We love a total commitment to a look. Call her Pop Star Goes to Paris Barbie.
