Mad Men cutie and forerunner for the-best-brows-in-Hollywood title, Kiernan tried out a whole new make-up style on the front row at the Rag & Bone show this NYFW. Her expertly applied OTT feline-flick eyeliner taps right into the 60s trend, which is appearing on next season’s catwalks, too (see Gigi Hadid’s gigantic beehive wig and drawn-on lower lashes at the Jeremy Scott show this week if you had any doubts).

Why it works? Kiernan’s high-volume updo and strawberry-pink lips are ultra modern, which keeps her look totally Y2K15 and not even a tiny bit fancy dress. Elegant, baby.
