Bella and Gigi Hadid walk Alberta Ferretti show in Milan

They boast millions of Instagram followers, endless fashion campaigns and have stomped down the runways of many an elite label.

And the Hadid sisters continued to blaze their trail of sartorial domination on Wednesday, as they slipped into sizzling swimwear to lead the glamour at Alberta Ferretti’s Spring/Summer ’18 show during Milan Fashion Week.

Bella, 20, oozed sex appeal as she slipped into a racy wraparound bikini top, while her older sibling Gigi, 22, exuded elegance in an understated black swimsuit that clung to her toned frame.

Bella looked every inch the catwalk queen in the sizzling string bikini top, which she teamed with stylish black tie-front shorts that flashed a hint of her toned stomach.

The brunette beauty put a fresh spin on summery footwear with a pair of black caged jelly shoes that featured heavy-duty stud detailing.

Injecting her chic look with an understated Nineties minimalism, Bella completed her look with a simple black masculine blazer.

Her hair was swept off her face into a tousled chignon, with tendrils artfully framing her face, while her striking green eyes were highlighted with a sweep of winged eyeliner.

Meanwhile, Gigi injected her swimwear with an irreverent dose of sports-luxe as she slung a black hoodie off her shoulders.

Oozing summery cool, her blonde locks were styled in a tousled braid and she boasted the same romantic smokey eyshadow as her sister. 

The sisters were joined by a bevvy of stunning models on the runway, including Brazilian bombshells Alessandra Ambrosio and Izabel Goulart.

Also ruling the catwalk was Joan Smalls, Isabeli Fontana and Karlie Kloss, as well as the Hadids’ close friend Hailey Baldwin – who stunned in a thigh-grazing silver minidress.

Their catwalk show comes after the sisters made a very early exit from her London hotel on Wednesday morning and looked undeniably tired.

But the sisters proved to be transformed later on in the day as they touched down in Italy for the upcoming Milan Fashion Week.

Bella oozed sex appeal with a figure-hugging keyhole white top, while her older sister, 22 – who donned the same ensemble from earlier on in the day – seemed to have made a glamorous change.  

Bella looked ever the style star in her all-white ensemble, which consisted of the skintight white top. 

The number boasted a large hole in the middle – teasing at her assets – before flashing a peek of her stomach with a split. 

Bella teamed the look with a pair of chic lace-up white trousers, which flawlessly showcased her toned legs. 

Meanwhile, Gigi, who was still casually clad in her comfortable grey jumper and matching joggers, looked sensational despite the early start to her day.

Several hours after storming the catwalk in her latest designs for the third TommyXGigi collaboration, Gigi was seen making an early exit from her hotel in the capital on Wednesday morning.

Despite appearing tired, Gigi still made for a stylish display, as she headed out alongside her sister Bella – still on cloud nine from her LFW success.

The blonde beauty, albeit fatigued, looked nothing but fresh-faced as she chose to forgo her make-up and flaunt her natural beauty in the early hours. 

She hid behind a pair of round-framed, purple-tinted sunglasses and left her long locks to fall past her shoulders in tousled curls that had been swept over to one side.

Opting for comfort, Gigi was seen sporting a matching grey tracksuit that paired together a loose fitted sweatshirt and casual trousers that billowed out around her legs.

He had told Harper’s Bazaar: ‘Gigi Hadid in my opinion is not only a supermodel – she is the star of today. She’s not only beautiful, but she’s a really nice person, she has her feet on the ground, she’s very intelligent and she looks amazing in our clothes.’ 

Gigi, who is dating former One Direction star Zayn Malik, had been joined on the catwalk for Tommy Hilfiger’s debut showcase by her sister Bella, Jourdan Dunn and Joan Smalls, with the models dazzling in the designer’s SS18 collection.

The much-anticipated showcase of Hilfiger’s SS18 collection brought a touch of sportswear chic to Fashion Week, closing the five-day event with a high-profile bang.

Following the success of the first two TOMMYNOW shows, the Fall 2017 event built on TOMMY HILFIGER’s signature “See Now, Buy Now” format.

For the first time, TOMMYNOW included both men’s and women’s collections, in addition to the third TommyXGigi collaborative capsule, and all runway looks were available across an ecosystem of immediately shoppable channels in more than 70 countries.

Gigi, meanwhile, was accompanied by Bella as she headed out in London the morning after the runway show, with her sibling dressing down in a velour tracksuit and lace-up boots.

The girls had been joined by their mother Yolanda, 53, throughout their time in London – having jetted into the UK after taking to the catwalk in New York for Fashion Week across the pond. 

The proud mother-of-three, who is also mum to 18-year-old son Anwar who also models, has openly spoken of how she wouldn’t let her children enter the fashion industry until they she deemed them old enough.

‘I never let them work [as models] before they were 18,’ she told ELLE.com. ‘I didn’t want anybody judging them on what they looked like. 

‘I wanted them to feel and be the authentic human beings that they are and I think that created a lot of strength for them.’

She continued: ‘I always said to them, listen, there are thousands of girls that are much more beautiful than you girls, but you have an extraordinary character.

‘And you’re going to have to set yourself apart by being a role model by showing up on time and being kind to everybody… that’s how you can make a difference in the world.’
