Well, hel-lo switch-up: Alexa Chung reminded us once again last night that she is a bona fide fashion killer by swapping her trademark shaggy going-out hurr for sleek double plaits. Bold. Now, if anyone can make schoolgirl plaits evening appropes it's the Chung (at London department store Selfridges to launch her nail varnish range Nails Inc: The Alexa Editions) and Alexa didn't stop her style switch-up there. She also experimented with a fresh-to-death peachy pink lip and all-over dewy glow. (Love. That.) Totally digging her chic Nehru collar embroidered blouse by Russian designer Vilshenko, with awks length trousers, too. Alexa tip: Undo the bottom two buttons of your blouse for added steez.
