Rosamund Pike has been unveiled as the new face of L.K. Bennett, following in the footsteps of fellow British actress Emily Mortimer.Shot in a Belgravia mansion by Mariano Vivanco, the ads showcase the brand's spring 2013 mainline and Black Ribbon collections of clothing and footwear. "I think that L.K.Bennett is the perfect brand for the working woman because it gives you that ability to feel dressed and polished without feeling overdone and I think that is the key to making you feel good and giving you confidence," said Pike. "It gives you freedom to play and that's what makes clothes exciting." L.K. Bennett has experienced an upturn in fortunes over the recent years, thanks in part to the Duchess of Cambridge. In a recent Vogue article, penned by the Telegraph 's fashion editor Lisa Armstrong, it was revealed that it has been the most-worn brand by the Duchess for official engagements. The pregnant Royal is a dedicated wearer of their £195 'Sledge' pumps in nude, sales of which - and also nude shoes in general - have reportedly rocketed since she first stepped out in them.
