Lily James put on a leggy display as she attended a screening of her film Relay at the SVA Theater in New York City on Saturday.

The actress, 36, looked incredible as she slipped into a purple mini dress with long sleeves and a turtle neck.

The garment highlighted the star’s jaw-dropping figure and Lily added height to her frame with a pair of matching heels.

Letting her locks fall loose down her shoulders, the Downton Abbey star completed her look with a pair of sunglᴀsses.

Earlier on the day, Lily stepped out in a white vest top tucked into a black mini skirt.

She wrapped up in a matching blazer and also wore black shoes and carried a small handbag.

It comes after Lily celebrated her 36th birthday in April at a Michelin-starred restaurant in North London with her famous friends.

The actress splashed out on a private dining room at modern Italian restaurant, Luca, not far from Lily’s Grade-II listed £3million home.

Hiring a private space at the lavish eatery which has a minimum spend of £650, with the chef’s fixed menu, including a wine pairing with each course, costs nearly £200 per person.

Lily was all smiles as she was joined by several close friends including her Mamma Mia! co-star, Dominic Cooper, his girlfriend, actress Gemma Chan, actress Gala Gordon and socialite Poppy Delevingne, older sister of model Cara.

Gala and Poppy took to Instagram to share pictures showing Lily looking happier than ever as she celebrated her day. 

She looked relaxed in a khaki sleeveless dress cut away at the waist, showing off her slender frame.

The Surrey-born star and her friends drank champagne and red wine while feasting on a menu with mouth-watering items including £68 beef ribeye, £49 lamb with spiky artichoke and pine nuts and fresh pasta dishes such as £46 prawn taglierini.

At the end of the meal, Lily was treated to a big white birthday cake adorned with multi-coloured candles, meringue balls and an icing pH๏τo of herself as a child in an early acting role.

‘Keep shining my girl – this is your year,’ her close friend Gala, 34, captioned a video online. Gala is an executive producer of Swiped, the film starring Lily as Whitney Wolfe Herd, the founder of dating app Bumble, due out this year. Gala is also co-founder of a film production company, Parados Productions, with Lily.

Poppy, 38, shared a video of her and Lily playing around in a lift, with a soundtrack of the quote: ‘You are by the far the baddest, raddest, Sєxiest, most far-out kick-a** chick that I’ve ever met!’

It is a line said by actor Sebastian Stan as Tommy Lee to Lily’s Pamela Anderson in the 2022 TV series, Pam and Tommy. 

‘You really f****** are,’ wrote Poppy, who is heavily pregnant with her first child – a girl – by her billionaire boyfriend, Archie Keswick. ‘Happy birthday beautiful LILS. Love you to Pluto.’

Lily, who has previously been in long-term relationships with actor Matt Smith and US musician Michael Shuman, did not appear to be joined by a date at her birthday bash.
