Last night, Gigi Hadid celebrated her 24th birthday in New York City, and naturally all of her famous friends came out to celebrate. The birthday bash's dress code was immediately obvious, given that almost everyone at the party dressed in head-to-toe denim. Gigi herself wore a denim jacket and bootcut jeans with a white tank top, while Bella and Yolanda Hadid, Ashley Graham, Alexandra Agoston, and Olivia Culpo all abided by the denim decorum as well. There were a few outliers, of course, including none other than Taylor Swift.
Swift nixed the denim theme and wore a Mango Houndstooth Coat ($170), Zimmermann Heathers Sundress ($425), and a cat-bedecked Anya Hindmarch bag. In case you haven't noticed, Swift has unveiled a new look on her Instagram in anticipation of an announcement on April 26, and she's also dressing accordingly in her saccharine printed dress and kitschy cat bag.
