The model turned 24 on Tuesday, celebrating the night before with a denim-themed bash at L'Avenue at Saks in New York City. The birthday girl was definitely feeling the love, as plenty of her closest celebrity pals stepped out for the party.
Gigi encapsulated the theme perfectly, rockin' distressed jeans and a denim jacket over a white crop top. She completed the look with a pair of comfy Doc Martens boots and plenty of jewelry.
Her sister, Bella Hadid, also dressed to impress, amping up her denim with hoop earrings, a smokey eye and her hair tightly pulled back into a chic bun.
BFF Taylor Swift put her own spin on the dress code, seemingly sticking to the aesthetic fans have been seeing all over her social media in anticipation of a new project coming Friday. The singer wore a red houndstooth coat from Mango over a Zimmermann floral dress, which she paired with Sanderson heels and an Anya Hindmarch cat bag.
Olivia Culpo wore one of the most glamorous outfits of the night -- an oversized denim zip-up jacket paired with glittery knee-high Jimmy Choo boots, a matching choker and hoop earrings.
Hailee Steinfeld also opted for boots, pairing them with a denim jacket and dress that featured tweed panels.
Of course, the party wouldn't be complete without Gigi's famous mama, Yolanda Hadid, who stole the show in a three-piece Canadian tuxedo paired with a leopard-print clutch.
Other celebrities in attendance included Ashley Graham, Marc Jacobs, Martha Hunt, Patrick Ta, Helena Christensen and Kendall Visser, along with Gigi's father, Mohamed Hadid, and her brother, Anwar Hadid.
