What better way to kick off a month-long whirlwind of fashion shows from New York to Paris than with a party?

That’s the idea Gigi Hadid followed on Tuesday, when the 21-year-old model stepped into Manhattan’s Flash Factory in celebration of V Magazine’s September issue. And while we’re counting down the minutes until the beauty makes her first run on the catwalk this season, she managed to steal the show, thanks to a graphic black-and-white jumpsuit that fit her like a glove.

The strapless Talbot Runhof design made for a whimsical optical illusion and stood out next to Hadid’s ankle-strap heels and black neckerchief. So what, other than fashion, is on the star’s mind? She took to Instagram on Wednesday to wish her older sister, Marielle Hadid, a happy birthday.

“Happiest birthday to my beautiful big sister and the BEST mom to my niece and nephew @mariellemama. Wish I could be with you today sissy. Love you endlessly,” she wrote alongside a gorgeous throwback image.
