Hollywood’s hottest names have been primping, preening, polishing and tanning for weeks in preparation for the biggest night in the fashion calendar - and a little shindig we like to call the 84th Academy Awards.

The stars may be vying for a highly coveted Oscar but there's really only one prize up for grabs – and that’s the Best Dressed celebrity of the night award (catchy).

Designers have been battling it out to dress the likes of Michelle Williams, Rooney Mara and Emma Stone for months while fisticuffs over who’s wearing who amongst the A-List ladies themselves are not unheard of either...

The Oscar for worst dressed goes to...

While Rooney Mara may’ve only decided to wear Givenchy Couture on the day (although as her go-to label of choice it hardly came as a shock) she, Angelina Jolie and Berenice Bejo all delighted onlookers in their bespoke gowns. But who was the BEST dressed star of the night?

That, dear 3am-ers, is up to you…

Cameron Diaz dazzled in aquatic-inspired Gucci, a big trend for spring/summer ’12 and added Tiffany & Co. jewellery (nice). Though we’re not yet convinced with her hair…is she your best dressed?

Milla Jovovich was one of the first celebrities to arrive in sequin Elie Saab but does she take home fashion first place?

Jessica Chastain wore bespoke Alexander McQueen plus $2 MILLION worth of jewels, but was it worth it?

Gwyneth Paltrow was the shock frock of the night, upping the WOW factor in Tom Fordm handpicked by the designer himself. Her mafia-style dress with cape detail is light years away from Gwyneth’s usual backless styles – but is it super enough for you?

Rooney Mara admitted she was pretty chilly on the red carpet and only picked her Givenchy Haute Couture by Riccardo Tisci gown that morning – but was it worth it? Givenchy is her preferred label of choice but did she do enough to win your vote?

Jennifer Lopez slipped on a slinky Zuhair Murad gown spun so finely it could’ve been made from spiders webs. Only it wasn’t, it’s designer (darlink). The singer added Lorraine Schwartz jewels to her look…

Angelina Jolie nevers fails to impress, although she certainly didn’t take any risks with this black velvet Atelier Versace dress. A little bit Kate Middleton, meets Jessica Rabbit thigh-high slit, did she do enough to bag your Best Dressed award?

Natalie Portman showed off a whole new look in 1950’s vintage Dior polkadots. The dress is stunning, the slicked back hair is a move away from her preferred ballerina bun style – but is her rockabilly frock more prom night than Oscar night?

Emma Stone had the fash’ pack all in a spin with her red Giambattista Valli gown and chic up ‘do. While most agreed the colour was red hot, that bow neck detailing divided many.
