Demi Moore wows in a floral embellished dress as she joins director Coralie Fargeat for The Substance photocall in Paris

Demi Moore showed off her impeccable sense of style as she was joined by French film director Coralie Fargeat at The Substance photocall in Paris on Tuesday.

The American actress, 61, exuded elegance in a pink and blue floral embellished dress as she posed up a storm at the event.

She teamed the ensemble with a smart black blazer before further accessorising with a pair of silver diamond drop earrings.

Meanwhile, the French filmmaker stunned in a deep burgundy strapless dress.

To complete her look, she opted for a black-and-gold choker necklace as she posed up a storm next to Demi.

In the film Demi stars as Elisabeth, an ageing TV fitness instructor a la Jane Fonda who signs up for a mysterious medical regime called The Substance that promises to create the perfect version of herself - played by Margaret Qualley .

Unceremoniously sacked as she hits her 50th birthday, Elisabeth discovers a black-market drug which can create a 'younger, more beautiful, more perfect' version of its user.

The drug's strict conditions are gruesome, however, and Elisabeth's need for youth to sustain her career talks directly to Hollywood's abandoning of actresses as they age.

But it's The Substance's 'deliciously unhinged and dread-inducing' levels of gore that have really commanded the critics' attention, with one describing it as 'a shocking assault on the senses'.

The one rule to follow is that Elisabeth and her better self Sue (Margaret Qualley) must trade places every seven days.

So for one week at a time, she is forced again to live as her 50-year-old self.

Demi said the vulnerability required for her role in the body horror film was both demanding and exciting.

The role required Demi to be completely naked as well as transform into a deteriorating old woman through prosthetics.

The actress said: 'All of it at different times had moments that were challenging. The level of vulnerability that this role called for on all the different levels - emotionally, physically - were as demanding as it was exciting because it was really pushing me to step out of my comfort zone.'

Critics were positive about her performance, with Variety calling it 'nothing short of fearless' and The Hollywood Reporter praising how she 'imbues her character with a visceral desperation.'

Director Coralie said that her goal for the film was to explore women's toxic relationships with their bodies and how they are taught that their worth is tied to their appearance.

She said: 'The way I wrote the movie really sticks to what we experience as women with our bodies. So, it's the way our body is seen, but also the way we see our own body.'
