AUSTRALIAN actor Nicole Kidman has turned heads on the Oscars red carpet, wearing one of the trends of the night: a nude-coloured dress.

The Oscar nominee is striking in a skin-coloured body-con dress.

But it was one actor's seriously high thigh split that turned heads for the wrong reasons.

American actor Blanca Blanco is wearing a dramatic, puff-sleeved gown with a split right up to her, um, hip, which led to an embarrassing (and inevitable) wardrobe malfunction.

Stars are getting political, sporting blue ribbons as a show of support for the American Civil Liberties Union in the wake of President Trump's controversial travel ban.

Supermodel Karlie Kloss, actor Ruth Negga and best original song nominee Lin-Manuel Miranda are all wearing the ribbons.

Nude and gold are huge trends, with Oscar nominee Emma Stone, Dakota Johnson, as well as Biel, sporting metallic looks.

Australian Hacksaw Ridge actor Teresa Palmer is stunning in a silver Prada dress and she's marking her 31st birthday at the Oscars (as you do).

Chrissy Teigen absolutely nailed her Oscars look, on trend in white.

Former Miss Universe Olivia Culpo - though not actually an actor in any way - looks polished in a custom-made Marchesa frock.

Culpo's one-of-a-kind Marchesa for Stella Artois gown featuring beads made from the Stella Artois limited-edition chalices. Her gown was made by Marchesa as part of a push to raise awareness for the global water crisis.

Meanwhile, Felicity Jones resembled a ballerina.

There's a lot going on with Hailee Steinfeld's Oscars dress - high neck, train, floral print.
