Jennifer, 48, looked as effortlessly sensational as ever, in a sleeveless black halter-neck dress, which flowed down her lithe figure and stopped in a ruffled effect just above her ankles.

A couple of sizeable slits in around the thigh area of the gown allowed Jennifer's toned and tanned legs to tease through the fabric.

She wore a pair of black killer heels on her feet, bringing her a little taller next to her handsome husband.

Jennifer kept her make-up as natural as ever, and her hair loose, looking very Rachel-esque in the way it was styled.

Make it a midi in Jennifer's skirt by Givenchy

Jennifer Aniston attended the Festival Serie Mania opening night in Paris yesterday alongside her husband Justin Theroux and what a gorgeous couple they made.

Justin looked cool but stylish in a striped tee, jeans and blazer while Jennifer showed off her fashion credentials in a cute black top which she tucked into this fabulous midi skirt by Givenchy.

From the Pre-fall 2016 collection it features two sexy cut outs at the thigh and a frilled asymmetric hem. It's flirty, flouncy and a little bit Flamenco and we love it. The good news is it's still available to buy and you can pick it up at a reduced price at Net-a-Porter now (right).

Or head to our edit below where you'll find more midis that'll give your wardrobe an elegant new season update. Splash some cash on Facetasm or bag a high street bargain at Marks and Spencer, River Island and Asos.

Style with a white tee and sneakers for a dressed down office look or dress it up for night with heels and a silky camisole.

The hunky star looked thrilled as he got snap happy with his blonde other half, who he wed two years ago. 

The lovebirds initially flew into the romantic European city earlier this week to witness Louis Vuitton's new collection at the Louvre.

Since then they have embarked on a number of outings in Paris - ensuring to make full use of their time before they head back to the US. 

In an interview with the Philippine Daily Inquirer, Justin held forth on the fact his and Jennifer's careers can fling them to different towns, away from one another.

'It’s tough; it’s a pain. But even though you are tired, you just make an extra effort to make trips back home, or have your partner come visit you,' he explained. 

Gossiped he: 'Keith Urban said that he once flew from New York, all the way to Australia, to have dinner with Nicole Kidman. Then, he flew back to his concert tour.'

With a laugh, Justin - whose role on The Leftovers takes him to Australia as well - conceded that Keith's 'a better man than I am. I would never do that.'

He and Jennifer had once resolved not to stay apart longer than two weeks at a time. 'Then, it would be a two-and-a-half-week rule. So, it’s a moving target.'
