The style-loving stars of The Only Way Is Essex aren't often upstaged when it comes to tight-fitting ensembles.

But as far as wearing jeans that look painted on, Ferne McCann's fashionable friends in Piccadilly Circus were literally showing off ever inch on Sunday.

Ferne, seemingly overdressed in a chic printed duster coat, joined nude models covered up in just body paint and thongs as she promoted new fashion app Grabble this weekend.

Ferne looked chic in white palazzo trousers and a festive silver T-shirt as she added her celebrity status to the brand's Christmas campaign, #GetDressed.

She mixed up her animal prints with a pair of snakeskin heels, which were offset by her leopard patterned jacket, which would have been the envy of her half-naked counterparts.

TOWIE star Ferne cosied up to female fashion faces who modelled 'bespoke' Christmas jumpers and black jeans as they stood outside in the London tourist hotspot.

Ferne will also be lending her style tips to the app, which features the same swipe function as Tinder where users can pick from their favourite trends and potential style purchases.

The reality TV star showed off her bubbly side as she indulged her personal interest in fashion, being the face of her own fashion collection for Lasula. 

While Ferne has her sideline in fashion, it has also been confirmed this month that her boyfriend Charlie Sims, a deli owner, is moving on from TOWIE to focus on 'other things.'

The star is said to have been 'unhappy' in his role on the show, which has primarily followed the emotional rollercoaster of his relationship with Ferne.

Co-star Billie Faeirs confirmed the speculation this week, telling OK! online: 'If you're not happy then there's no point in staying somewhere.

'That's why Charlie left, he needed to take the time away to concentrate on other things.' 

She added: 'He's left but I think the door has been left open for him. It's really benefited him and Ferne's relationship too.'
