British-born Alexa Chung began modeling in London at age 16 and later graduated to TV work, eventually coming to New York in 2009 to host her own MTV show, It's On With Alexa Chung. The show didn't last long, but it turned Chung into a fashion-world darling, and she quickly became ubiquitous at fashion shows and parties. Known for her eclectic taste and ability to cobble together unexpected combinations like corduroy shorts over wool tights with open-toe shoes, she almost single-handedly kick-started trends like ombré-dyed hair and socks with sandals. Described by Jane Keltner de Valle as “the Kate Moss for this new generation," Chung is somewhat of a fashion chameleon, but she often sticks to buttoned-up necklines, short hems, and her trademark mussed hair.
