Bella and Gigi Just Met Back Up on the Balmain Runway

Bella stepped onto the red carpet at Vogue's 95th anniversary party in a black sheer Balmain dress that featured a caged design and chiffon ruffles.

Bella turned to the side to show off her jaw-dropping bootylicious look.

Meanwhile, Gigi chose to debut her Versace runway look on the red carpet at Vogue's anniversary party. She finished her vibrant, textured dress with the same orange and purple platforms she wore on the catwalk.

The sisters stuck together while heading into the Balmain after-show party.

Gigi walked the Balmain runway in a bronzed look, baring her midriff in a halter neck crop top and matching her golden skirt to a statement choker.

While Gigi sported natural colors, Bella went all-black in a belted formfitting midi that boasted sheer panels. Her outfit was complete with a thick metal choker, wide geometric belt, and strappy heels.

Bella struck a pose backstage with Lily Aldridge and Lily Donaldson.

Meanwhile, Gigi stood by her right hand man backstage, Kendall.

Gigi and Bella stepped out at the Harper's Bazaar Icons Event, making a night of it to celebrate the end of NYFW. They posed with Kendall and Stephen Gan on the red carpet.

Gigi gave us a peek at the H&M x Balmain collection in this embellished graphic print minidress from the collection. She finished her outfit with simple strappy pumps.

Meanwhile, Bella showed up to the party in a romantic black gown that featured sheer lacy panels. She played up her glow with a pendant necklace and glittering clutch.

Gigi and Bella went out for dinner with Carine Roitfeld's crew. Kim Instagrammed a photo from the party with the caption, "Girls Girls Girls Girls @carineroitfeld @gigihadid @bellahadid."

Gigi worked a ribbed turtleneck dress, complete with a leather panel, with a pair of lace-up Rodarte boots that made our jaws drop. Instead of opting for a delicate lacy design, Gigi stuck to her signature style and went the sporty route.

Meanwhile, Bella interpreted the lace-only dinner dress code in a laid-back fashion. While her high-waisted trousers and embellished leather Chrome Hearts jacket were casual-cool, her top — a triangle lace-bra layered beneath a sheer cap-sleeve shirt — was supersexy.

Gigi opened the Jeremy Scott show in a pink and orange shiny set and eye-catching yellow heels.

Bella wore a polka-dot button-down crop top with tight pedal pushers. She wore a couple of bangles and complementing orange pumps, making for a poppy, playful '50s look.

Bella walked the Jeremy Scott runway in a high-neck sequin-embellished babydoll dress that was complete with fishnet tights and zipper-clad ankle booties.

Gigi's second Jeremy Scott look was a sexier take on her sister Bella's. Rather than a dress, Gigi showed off a pleated mini and a sexy silver bralette we could see Katy Perry or Miley Cyrus rocking.

Teen Vogue shared a BTS snap of Gigi and Bella preparing for their beach-ready looks at Tommy Hilfiger.

Gigi walked the runway twice at the Tommy Hilfiger show, debuting this gorgeous crochet-finished maxi dress first.

Gigi showed off her bikini body in this Rasta inspired swim look.

Bella let her crochet triangle bikini peek through her mesh tank, which was complete with a pair of luxe suede tie-waist trousers, statement jewelry, and colorful sneakers.

Gigi and Bella both took a turn posing with Tommy Hilfiger himself backstage.

Bella looked casual-cool, standing next to Tommy in her suede trousers.

"Two sisters. . . love and complicity. . . @gigihadid @bellahadid both in my fashion show this afternoon," DVF teased on Instagram before the show.

She later posted a stunning BTS shot before they walked the runway.

Gigi glowed on the runway in a sheer maxi dress that featured a plunging neckline and gold embroidery.

Bella's look was a bit more playful: a wide-leg, zipper-adorned jumpsuit printed with a colorful pattern. Her design was accessorized with a neutral fringe clutch and a stack of bangles.

We got a side view of Gigi's intricate braids, which weaved through bright flowers.
