She completely stole the show in Cannes this week in a red Alexandre Vauthier silk wrap gown with a plunging neckline and a thigh split so eyewateringly high it ruled out the possibility of wearing underwear.

Bella Hadid, 19, looked as if she was millimetres away from a serious wardrobe malfunction with every pose she struck on the red carpet at the Unknown Girl premiere.

But now the model's stylist Elizabeth Sulcer, has revealed that the secret weapon that meant the star wasn't at risk of revealing too much - a hidden built-in bodysuit.

She's taken the crown at Cannes over the last couple of days, and Bella Hadid is once again making waves on the red carpet this evening at 'The Unknown Girl' premiere.

Showing off her enviable figure in a daring slinky red dress with plunging neckline and thigh high split, Bella was leaving little too the imagination in this number. Red is always a definite show stopper but add in both cleavage and leg and you've got a seriously sexy look. We're not sure if anyone else is going to top this one tonight! Bella's dress is by Alexandre Vauthier, a brand she's favored on the red carpet before and part of the brand's SS16 couture collection.

If you want to make an entrance at your next party or event, a slinky red dress could be the way to go. To steal Bella's style, shop our edit of red maxi's below. Bec & Bridge have a great option which has both the side split and the plunge neckline so bag that one at Asos. Otherwise got short at Boohoo, or lacy at Forever 21.

You won't need much in the way of accessories with a dress like this so take tips from Bella and opt for a sleek up-do and simple black strappy sandals.

Speaking to Vanity Fair, the stylist revealed that she and Bella had worked together with designer Alexandre Vauthier to create something 'beautiful and iconic', saying: 'Every aspect of the dress was planned.'

Asked what was going on underneath the dress and if she had any tips for wearing a similar wisp of silk, she replied: 'The dress has a built-in silk bodysuit. Top-stick tape is always a good idea. Practice makes perfect.'

It explains why the model looked so confident as she posed up a storm on the red carpet, seemingly untroubled by the fear of revealing too much. 

Bella's dress was completely backless with delicate spaghetti halterneck straps.

Breaking the age old advice of only showing legs or cleavage Bella did both, flaunting her curves and showing off her sideboob in the barely there top.

Her dress then extended into a slinky skirt which featured a lengthy train and a thigh high split.

However, she admitted that every tiny detail had to be taken into consideration noting that having the dress fitted is not the same as being able to make it work on the red carpet.

Stylist Elizabeth Sulcer revealed she wanted to create a 'beautiful and iconic' look for the model 

The model wasn't shy about showing off her cleavage in the plunging halterneck dress 

'Bella is smart and confident, and we knew she could wear that dress,' she said.

She revealed that the pair had spent a lot of time working on Bella's red carpet looks for the film festival and they are 'very focused and organised'. 

And unsurprisingly, she declared they were both happy the dress is having a 'lasting impact'.

Her stylist said she knew Bella had the confidence to pull off such a daring look

However Bella is by no means the first to make such a drastic style statement. 

Singer Rita Ora wore an equally out there gown for the MTV VMAs in August 2014 showcasing the same thigh-high split, plunging neckline and bright red shade.

However, her gown was made by Donna Karan and didn't feature the same detail on the waist as Bella's.
