New York fashion week has kicked off and who better to wave the fashion flag than Alexa Chung, AKA Williamsburg’s most stylish expat.

The feathered shift is so SS14 Sixties gal-about-town but we're most jealous of three things here: Alexa’s tan, dem glossy waves and those Gucci boots. To. Die. For.

Wanna see how Alexa is simultaneously nailing midi-season dressing? It's all here...
