Check out our Best Dressed List for 2012 and see who's been impressing in the style stakes.
She's French, she's beautiful, and she's unbelievably stylish, Marion Cotillard is up there with our fashion favourites. This was our favourite look of hers from the year, a houndstooth Dior dress paired with colour pop red heels and a faux bob. Divine!
Camilla Belle is always flawlessly turned out, here she's gone for a particularly vampy, flapper girl inspired look in a silver plunge-neck evening gown.
It wouldn't be a Best Dressed List without the omnipotent style icon Alexa Chung. No-one does kooky high fashion like the Chung, and her ever-changing hairstyles are the envy of women across the world!
It's been a great year for the Duchess of Cambridge Kate Middleton, and she has shown time and time again that she has impeccable fashion instincts. Chic, elegant, ladylike.
High fashion queen Diane Kruger LOVES her clothes, and she isn't afraid of experimenting, and sometimes looking a little bonkers in the process. Here she wears a spectacularly voluminous Dior haute couture dress and pulls it off with aplomb.
Gwyneth Paltrow is impossibly chic, even in her 'downtime' outfits, and here she works a cape better than any superhero. She stole the show at the 2012 Oscars in this wonderful Tom Ford creation.
We love Julianne Moore here in the RTÉ Fashion office, and here she shows just how unpredictable she is on the red carpet in a bright yellow Christian Dior haute couture gown. Always a winner.
Sarah Jessica Parker can always be counted on to step out in the most bang up to date ensembles, complete with to-die-for accessories and the most glamourous hairstyles. Here's one lady who will always inspire in the style stakes.
Jessica Biel has been hitting the red carpet in increasingly fabulous creations, we adore this baby pink Dior number on her (are we sensing a pattern here, Dior are ruling the roost when it comes to the red carpet!)
Emma Stone never fails to impress on the red carpet, and always goes for really idiosyncratic looks that you won't see elsewhere. This navy and emerald peplum ensemble is one of our favourite style outings for the actress.
The amazing Jessica Chastain channels old-Hollywood style in this Giorgio Armani white dress. Everything about this look is impeccable!
Kate Bosworth can do no wrong as far as we're concerned, and the actress looked particulary adorable in this Burberry ensemble.
Kristen Stewart has been going for increasingly daring red carpet options as the year progresses, however, we like it best when she sticks to her own grungy aesthetic. This look is cool, laidback and utterly her own.
Kate Moss rocked it in this Stella McCartney illusion cocktail dress and Louboutin heels, a super look for the reigning supermodel.
It's been a fantastic year for Brit model Cara Delevigne, and we are loving her unique take on style. Here she rocks a metallic Burberry dress and wedges, and her eyebrows are just as inspirational as her dress sense!
The ethereally beautiful Rooney Mara had a fabulous run of avant garde red carpet numbers while promoting The Girl with the Dragon Tattoo, here she wows in a backless white evening gown.
Now THAT'S how to do Paris Fashion Week, Leelee Sobieski wowed in this Dior haute couture number in September.
Angela Scanlon's fashion star is on the rise, we love the Irish stylist's cool dress sense, which is utterly individual.
Helen Mirren never puts a foot wrong in the style stakes, we adore her chic and fun approach to fashion.
Rita Ora has been really impressing this year with her red carpet choices. She stunned in this red lace Marchesa gown at the MTV Awards.
Dita Von Teese is a lesson in old-school grooming, never seen without a perfectly applied red lip and curled hair. We love her vintage-inspired style.
Olivia Palermo: darling of the fashion world, style icon, wearer of amazing shoes. This is a lady who knows how to accessorise with abandon!
Liv Tyler has one of the most covetable wardrobes in Hollywood, and her sleek red carpet looks are matched by her super-cool off-duty looks.
Anne Hathaway has really come into her own on the red carpet in the past year, with a string of fabulous dresses while promoting The Dark Knight Rises. Here she shimmers and shines in nude Valentino, simply divine.
