Alexa Chung cut a stylish figure in a plain black dress at 16Arlington's show on day two of London Fashion Week on Saturday.

The model turned presenter and fashion designer, 40, stunned in a rounded square-neck dress as she joined Canadian model Sabrina, 34, and Bridgerton actress Simone, 28, on the front row. 

Alexa showed off her model physique in the dress which was tight fitting at the waist with an asymmetrical layered skirt at The Curve Gallery of Barbican centre. 

16Arlington was founded by Italian designers Marco Capaldo and the late Federica ‘Kikka’ Cavenati in London in 2018.

Sabrina, who is married to actor Idris, opted for casual chic as she wore a pair of black and white converses to the event. 

The model wore a smart black blazer, which she rolled up at the sleeves, over a tucked in white slight V-neck T-shirt.

She also wore loose, straight-legged trousers and she carried a small black backpack covered in large blue sequins. 

Simone looked glamorous in a huge cream faux fur coat which she teamed with a grey mini skirt and a sleeveless turtleneck jumper with cut-outs at the shoulder. 

The actress was all legs as she completed her look with white shoes with low heels and a pretty black purse. 

She will star in the third series of Brigerton which will controversially air in two parts in May and June.

Also there was Game Of Thrones actor Sebastian Croft, 22, who looked stylish in a tight blue top and baggy grey skort. 

This year's London Fashion Week kicked off on Friday and ends on Tuesday.

It comes after Alexa and her boyfriend Tom Sturridge once again sparked engagement rumours.

The model and the actor, 38, stepped out for the 18th Rome Film Festival at the Auditorium Parco Della Musica with matching rings.

Alexa looked as fashionable as ever in an all-leather ensemble including a chic coat tied at the waist.

Leading man Tom looked smart in a black suit as Alexa supported him on the big evening.

He previously dated - and has a child with - British-American actress Sienna Miller.
