Roger Federer, the 17-time Grand Slam champion and one of the most elegant men to ever grace a tennis court, has come out of nowhere to show you how to do smart autumn style right.

Taking to the streets of Paris for Fashion Week, the Swiss maestro showed a previously unseen aptitude for slick European style, proving that it's not just sportswear that he can wear with panache.

We do understand that the roll-neck is a polarising item for a lot of you, but as Federer proves, it can be an invaluable piece for elevating your tailoring during colder months. 

Hover over the links below to see how Federer got it so right, as well as one small, avoidable pitfall that can make a big difference to your finished look.
