In a new photo posted to her Instagram, Kardashian looked like the definition of summer in her pearly platinum color and a vibrant siren red lip. Kardashian, who had light hair as a kid, has experimented with practically every shade of the blonde spectrum in recent years, but this may be her brightest, blondest look ever. (As a former platinum blonde myself, I know how fun it is to go lighter … and lighter … and lighter.) Her roots are invisible, leading me to believe she recently visited the salon for a touch-up, and the color is perfectly toned to a uniform platinum hue without any brassy patches or lilac tone from too much purple shampooing. (Been there.) Kardashian wore her hair in long, loose waves, which kept the look modern and not costumey with the red lipstick and her vintage-inspired dress.
