She sparked something of a hair revolution when she plumped for a drastic pixie crop in 2010.

So no doubt Emma Watson‘s latest magical transformation will prompt fans to follow her lead once again, after she debuted her latest cropped haircut on social media.

Naturally, the 25-year-old’s new cut was truly stylish and teased into light waves perfectly for Wednesday night’s The True Cost screening.

New ‘do: Emma Watson revealed her new, shorter and more chic hairstyle on Tuesday night via Instagram

‘Amazing woman. Amazing new hair,’ read the caption beside a striking picture of Emma and her new ‘do, which is a departure from the long, glossy brunette lengths she’s been sporting of late.

The cut, which features a lighter, dark-blonde colour, is characterised by a short back and long soft strands to frame her face at the front.

Formerly, the actress went from pre-teen screen queen to fully-fledged style maven at the age of 20 when she finished the Harry Potter franchise and cut off all of her hair.

Stylish: Emma was seen arriving at a screening for new documentary The True Cost in central London on Tuesday evening, where she sported the new hair ‘do

She told Metro at the time: ‘I didn’t get to experiment with dyeing and chopping off my hair like most teenagers.

‘I also felt, right, I’m 20, I’m not a little girl any more. I’d been on Harry Potter for ten years so I needed to mark the end of it in some way. I needed a drastic change and that’s what the crop was all about.’

Emma was simultaneously picked as the new face of Burberry and so began her transformation from child star to Hollywood leading lady.

Showing her enduring appreciation for film, the star was attending a film screening as a simple guest, rather than a headline star, on Tuesday.

She had been out and about to see new documentary The True Cost in central London but she couldn’t resist making headlines with her stylish appearance.

The 25 year-old, who was born in Paris, looked effortlessly chic as she emerged at from her car at the private event in Mayfair.

Wearing a navy knitted dress and Paul Andrew heels, the former Harry Potter actress appeared confident and calm as she made her way into the cinema.

Capping her ensemble with a tan coat, she was certainly dressed for the weather – yet refused to forfeit her sense of style.

Sporting fashionably tousled hair, the outspoken performer also wore plenty of tan-themed make-up, which gave her an unlikely glow for December.

However, she was evidently keen to make an effort for the evening, which celebrated the UK distribution of Andrew Morgan’s recent documentary, The True Cost.

Already the toast of critics, the film charts the human expense of so-called ‘fast fashion’ – with staff working in sweatshops.

Moved by the project, Emma recently adopted the cause as her latest social justice warrior role.

Taking to Instagram to share details of the ideas behind it, she posted an image of a clothes rail, saying: ‘Inspired to consider the whole process of creating a fashion look, we are thinking about all the people, pieces and moving parts!

‘This rack includes designers that are considering local craft and production, artisan s𝓀𝒾𝓁𝓁s, the environment, sustainability and the longevity of fashion!’.

At the screening, Emma joined actor Colin Firth and his wife Livia, who is founder and creative director of ethical company Eco Age Ltd, who champions sustainable clothing.

Also in attendance was Colin’s Bridget Jones’s Baby co-star Patrick Dempsey, model Erin O’Connor and director Andrew.
