You know when Alexa Chung hosts an event, Fashion Week is really beginning. Such was the case yesterday at Barneys New York's event for Carven designer Guillaume Henry. While we'll be bringing you a full roundup of the pics, we couldn't wait to show off Chung's absolutely obsession-worthy nail art. A pretty perfect escape from outdoor's gnarly wintery mix, the model turned her nails into a tropical escape, with white polish hosting '70's-style palm trees. And, against that croc Miu Miu, well...we die.
