But Anne Hathaway went in a different fashion direction on Wednesday, when she promoted new film Les Miserables in a sheer black dress.

Joined by co-stars Hugh Jackman and Amanda Seyfried, the A-lister gave the audience a little more than they were expecting when she took to the stage during a photocall in Tokyo.

Sheer daring: Anne exposes more than expected as she takes to the stage to promote the film

On first look, it seemed like the Hollywood star was wearing a floor-length, black gown, but on closer inspection the skirt was obviously sheer.

 

Luckily the Batman star had a short black skirt attached to the dress, preserving her modesty but still making sure that the outfit was edgy.

Anne seemed to be growing her elfin hairstyle, which she had chopped off for the film, as wisps of fringe fell into her eyes.

Wearing minimal make-up and barely any jewellery, the actress made sure that the emphasis was on the halter-neck dress, which she paired with black kitten heels.

The 30-year-old star was joined by Amanda, who opted for a slightly oriental style dress for her trip to Japan.

Making the most of her long legs in a thigh-skimming skirt, the blonde actress added a pair of black tights and high ankle boots.

Her short dress was patterned and clinched in at the waist with a small black belt, accentuating her tiny figure.

The actresses were joined by Australian actor Hugh, who looked suave in a tailored grey suit and grey shirt, and put a protective arm around his co-stars.

The crowd seemed ecstatic to meet their idols and Anne went down to the audience to meet them after chatting on stage about the film.
