The Vanity Fair 'Best Dressed' list for 2015 is here, and it is more than a little surprising...

Best dressed woman goes to the UK First Lady, Samantha Cameron. The Prime Minister's wife may be a creative consultant for luxury leather goods purveyor Smythson, but it is a little surprising to see her beat the likes of Rihanna (6th place), Amal Clooney (5th place) and Taylor Swift (2nd place), is it not?

Meanwhile actor Bill Nighy, whose style icons include "Frank Sinatra, David Bowie, Bryan Gerry and Pharrell Williams" is crowned the number one best dress man for 2015. Nighy beats financier Stavros Niarchos III (2nd place), Apple's Jonathan Ive (5th place), and Prince Harry (8th place).

The 2015 'Hollywood' list sees Louis Vuitton's new girl, actress Alicia Vikander take the top spot at number one, whilst Eddie Redmayne comes in a close second. Redmayne reveals that his style icon is his father and his favourite designers including "McQueen, Valentino, Hardy Amies, and Private White V.C."
