- the best-dressed list
Beyoncé Knowles, 31
We've long been fans of the US singer's unapologetically glamorous look – she's come a long way since the days of her hand-sewn Destiny's Child stage outfits. Now, she pulls out all the stops on the red carpet in Lanvin, Roberto Cavalli and Givenchy.
Emma Stone, 24
The American actress is a born rule-breaker. From a plunging jumpsuit at The Amazing Spider-Man premiere to a green Gucci tuxedo at the People's Choice Awards, her imaginative style looks right every time.
Livia Firth, 43
A champion of ethical dressing, Mrs Firth is living proof that green can be glamorous. The global ambassador for Oxfam credits her fashion conscience to her Italian roots: "Italian women wear their clothes for years. They buy good-quality pieces that will last."creditsPhotographs: Landmark Media; Getty Images; Rex Features
