Gigi Hadid's birthday party crew got decked out in Canadian tuxedos – and it's everything

Supermodel Gigi Hadid rang in her 24th year around the sun with the most unintentionally Canadian party of all! Her biggest wish? That all her party guests – from Ashley Graham to Olivia Culpo and her sister, Bella Hadid – wear head-to-toe denim (a.k.a. a Canadian Tuxedo!). When it came to fashion, the 24-year-old's Midtown, New York City bash at L'Avenue didn't disappoint.
