Margot Robbie wears her boldest Barbie look yet at London premiere

Margot Robbie has worn her most 'barbie-esque' outfit yet to the London premiere of the highly-anticipated film.

The 33-year-old actress wore a custom pastel pink Vivienne Westwood gown which featured a huge off-the-shoulder ruffled collar and a flowing train.

For accessories, she wore clear Barbie-style heels, white opera-length gloves, and a triple strand pearl choker. According to Page Six, the look is inspired by the Barbie Enchanted Evening doll from 1960.

Stylist Andrew Mukamal has been helping Robbie recreate one iconic Barbie look after another over the past couple of weeks.

At the LA premiere, the Australian actor paid homage to the 1960s Solo in the Spotlight Barbie, wearing a Schiaparelli Haute Couture strapless gown with Lorraine Schwartz jewellery and Manolo Blahnik heels.

On June 25, at a photocall for the upcoming film, Robbie wore a polka-dotted Valentino minidress based on 2015’s Pink & Fabulous Barbie.

And a few days later, when she arrived in Australia for the press tour, she wore a black-and-white striped Hervé Léger look inspired by the original doll’s swimsuit from 1959.

At the Seoul premiere on July 2, she channelled 1985’s Day-to-Night Barbie with two hot pink looks and the following day at the press conference she wore a bedazzled jacket, skirt set and pillbox hat inspired by 1964’s Sparkling Pink Barbie.

Also attending the London premiere was Ryan Gosling, who plays Ken to Robbie's Barbie.

The first reactions to the film have started to surface online.

"Barbie is a triumph. A pitch-perfect script backed by great performances — particularly from Ryan Gosling — turns what could be a simple studio comedy into a sharp commentary on our society that makes its nuance palatable for those that may not take it at face value," one person wrote.

"I can't officially quit Twitter before telling you all that #Barbie is currently my favourite film of the year. Greta Gerwig somehow exceeded my expectations. She tackles the positives and negatives of Barbie so beautifully. Give Ryan Gosling an Oscar nomination, I'm dead serious!" wrote another.

Barbie opens in cinemas across Australia next week.
