She is undoubtedly one of the most beautiful women in Hollywood, but Jessica Chastain has shown she can turn a fashion craze into a couture classic.

The beautiful redhead was arrived at the Saint Laurent Fall/Winter 2013 Ready-to-Wear show in Paris looking ultra glamorous in a plunging red dress - which perfectly suited her pale complexion.

Opting for three-quarter length sleeves made sure the dress was perfectly demure and with lashings of red lipstick Jessica looked like she could have been on the runway - rather than simply front row.

Teaming the look with some delicate stilettos and her hair swept back, Jessica made sure she was the picture of perfection.

And it wasn't just Jessica who dressed to impress, Hollywood actress Kirsten Dunst also looked ultra chic as she attended the same show with boyfriend Garrett Hedlund.

The Bachelorette actress opted for a silky blouse and natural make-up as she watched the show from the front row with her dashing actor beau.

Earlier on in the week Jessica showed that classic fashion is often best as she turned heads sitting front row with Sylvie van der Vaart at the Viktor & Rolf show during Paris Fashion week.

The pale and interesting actress, who was dressed head to toe in the designer, wore a pair of cigarette black trousers with a black waistcoat and a pair of simple black heels.

However it was her hair and make-up which added that extra jazz to her look as her hair had been styled into Hollywood type curls.

Her eyes were accentuated with smoky eye make-up and she pulled her whole look together with a dash of red lipstick.

Dutch Sylvie also wore black trousers and a black top which featured interesting silver detailing.

Her hair was swept back off her face creating dramatic affect with a pair of silver shoes.

The Zero Dark Thirty actress’s visit to Paris came after she decided to share the best moment of the Oscars for her in a touching blog post. 

Rather than her favourite moment of the Academy Awards being to do with the glitz and glamour, it was taking her grandmother as her date.

'There was a special moment... while watching Barbra Streisand sing Memories. I looked over at my Grandma and she had tears in her eyes,' wrote Jessica.

'It was wonderful to be there with her, watching her favorite singer perform her favorite song.'

It was her grandmother Marilyn who encouraged the young Jessica's interest in acting, taking her to see a production of Joseph And The Technicolour Dreamcoat when she was seven years old.

But while the 35-year-old was enjoying her night with her supportive grandmother, she admitted in her blog post that the week was 'intense'.

The day before the Oscars Jessica missed the funeral of her estranged father Michael Monasterio, following his death from pneumonia aged 55.

The rock musician was aged just 20 when his daughter was born and played little part in her childhood, with her stepfather raising her as his own.
