Alexa Chung put on a leggy display as she headed to the Vogue World after party in Paris on Sunday. 

The model, 40, looked sensational in a gold embellished mini dress by CELINE by Hedi Slimane as she was joined by her rumoured fiancé Tom Sturridge, 38, at the star-studded event at Maxim's. 

The stylish ensemble boasted a round neckline, long sleeves, a gold diamante embellishment all over and an A-line skirt. 

She added inches to her supermodel frame with a pair of black strappy stiletto heels, while opting for natural hair and makeup. 

Alexa later took to her Instagram to share some late-night snaps with her followers. 

In one snap, the TV presenter looked incredible as she struck a sultry pose in a dimly lit bathroom, before grabbing a late-night snack after all the festivities in another image. 

Alexa and Tom made a seriously stylish pair as they arrived at Vogue World: Paris at Place Vendome in the French capital earlier on Sunday evening.

The model looked stunning in a CELINE by Hedi Slimane champagne dress with a chic red rose design, which she styled with a pair of heels in the same shade.

She further accessorised with a pair of cream sheer gloves and drop earrings, while styling her brunette tresses in soft waves.

After recently sparking engagement rumours, Alexa wore a diamond ring over her glove, as she flashed the sparkler as she arrived at the event.

Meanwhile, her rumoured fiancé looked dashing in a white jacket, which he wore over a dark T-shirt with a pair of trousers and dress shoes.

The actor kept the look cool with a pair of Wayfarer sunglasses.

A cohort of famous faces is taking part in the sold-out Vogue World event, celebrating 100 years of fashion and sport in the iconic city. 

Guests include Gigi Hadid, Ciara, Maluma, Sabrina Carpenter, Emma Chamberlain, Kendall Jenner, Serena and Venus Williams, Bad Bunny, and Aya Nakamura.

The venue for the show is the famed Place Vendôme - a square which is a renowned location for fine jewellery and the inspiration for a Catherine Deneuve film.

Last year the event was hosted in London, while the year before the Big Apple was the backdrop for the high fashion extravaganza. 

Those who were unable to get a ticket for the event will be able to watch the action unfold on a live stream, which will be hosted by Cara Delevingne.

This year's Vogue World collaborated with youth athletic academies across France, pairing different sports with a history of 100 years of French fashion.

The sports include cycling, gymnastics, tennis, fencing, and break dancing, among others and the fashion will shine a spotlight on both modern and historic designers.

Artists who are expected to perform during the show include Bad Bunny and Aya Nakamura, although little detail has been revealed so far. 

Speaking at the event, Vogue's global editorial director and Condé Nast chief content officer Anna Wintour, said: 'If Vogue World: New York was a street fair, and Vogue World: London was a glamorous night at the theatre...

'Supporting arts and cultural organisations in London – Paris will be a kind of opening ceremony; one that celebrates 100 years of fashion and sport, as well as this extraordinary city.'

A percentage of the net proceeds from ticket sales will be donated to the humanitarian organisation Secours Populaire. 

The organisation facilitates access to essential equipment for young, aspiring athletes across France.
