Daisy Ridley's gown for the world premiere of 'Murder on The Orient Express' took 65 hours to create.

The 25-year-old actress - who portrays Mary Debenham in the mystery movie based on the late Agatha Christie's classic novel of the same name - adorned a custom-made Vivienne Westwood dress to the star-studded premiere of the film, which took place at London's Royal Albert Hall on November 2.

Daisy and her stylist enlisted the help of Westwood's designer Andreas Kronthaler to create the piece, which took a team of three people over three days to perfect because over ''40 metres'' of various coloured tulle fabric was used.

Speaking about the 'Star Wars: The Force Awakens' star's show stopping attire to Vogue.com, the creative mastermind said: ''The meticulous layering of 40 meters of emerald green, violet, and soft ballet pink fine tulle and organza was [done] to create a delicate and mysterious gown paying homage to the glamour of 'Murder on the Orient Express'.''

And the masterpiece was inspired by ''the mysterious and unique'' shade of Daisy's eyes.

Kronthaler added: ''The gown is inspired by the mysterious and unique colour of Daisy's eyes.''

Kronthaler has admitted he is ''very happy'' with the outcome and thinks the dress looked ''so lovely'' on the brunette beauty, who swept her dark locks up in a neat bun to ensure all eyes were on her ensemble.

He said: ''Daisy looked so lovely in her emerald green gown. We are very happy to have created this especially for her.''

Meanwhile, Daisy has revealed she is surprised she landed a role in the film, which also stars Dame Judi Dench, Kenneth Branagh and Johnny Depp, because she feared she wasn't good enough for the part.

Speaking at the red carpet event, she said: ''It was amazing and what was more amazing was that everyone was absolutely lovely. I did feel really part of something.

''There were points I was like there's no way I was going to get this job, I'm not good enough.

''And then when you get to a point where everyone's made you feel so welcome it's just unbeatable.''
