It's official: winter is upon us - but that does not mean you have to sacrifice on style. A stream of fashionable femmes have provided us with excellent examples of how to look chic off-duty in a cosy cover-up. During Paris Fashion Week, we spotted Emma Stone trotting through the streets working the hottest trend du jour - leather accents - while Amanda Seyfried went the minimalist route courtesy of her camel coat. Leighton Meester's polished perfection also had as agog when she stepped out in NY and Fearne Cotton has kept us entertained with her carousel of winter warmers. So whether you make like Rihanna in a military-inspired get-up or go ladylike with a clinched waist a la Anna Kendrick and Dianna Agron, take some coat-spiration from this week's finest crammed into the gallery above. You'll be thanking us when the chill sets in!
