Laidback chic: Cara Delevingne, 24, as she stepped off the Eurostar in London on Tuesday after two and a half days in the city of lights

Her relaxed two-piece swallowed her slender frame as her loose-fitting joggers hung low on her hips, while attempting to cover her face from the waiting flashes.

The fashion muse looked ready to take on the city as she pounded the pavement in a pair of lace-up trainers, that teased at her teal socks on show.

Style darling Cara kept warm in a chic black coat, injecting some extra style points thanks to her Chanel choker, circular retro shades and studded leather backpack.

Her icy blonde locks were styled in a severe side part with a shaved section on display near her temple.

Also arriving into the city following her successful show at PFW was designer Stella McCartney in her ankle-grazing grey jacket.

The wide lapel wool piece made her look effortlessly chic as she stepped off the train, pulling her luggage behind her.

The sunglass clad 45-year-old strolled through the station wearing bootleg denims, a navy long sleeved top and her statement cross-body bag over her shoulder. 

Making a sartorial display off the Eurostar, Victoria's Secret Angel Lily Donaldson wrapped a shearling soft leather jacket around her leafy frame as she welcomed the London chill.

Taking a leaf out of Cara's style book, the 30-year-old showcased her enviable pins in a cream pair of joggers while covering her model features with a pair of large sunglasses.

Meanwhile, David Furnish, 54, followed the style brigade through the international station equipped with his luggage in both hands.

The husband of Elton John appeared to take inspiration from the city of love as he stepped out in a black turtleneck, suit trousers and eye-catching camel coat.

The pair had been the best of friends and inseparable in 2013, but have rarely been seen together of late.

Last year, it was reported the pair were reconnecting after reportedly falling out of touch due to Rita's then serious romance with Calvin Harris.

A source told Grazia magazine: 'They are rebuilding their friendship and Glastonbury was a big part of that.

'It’s been a long time coming but they are friends again,” a source told Britain’s Grazia magazine.'
