Gigi
Hadid

She is the elder Hadid sister, the one with the wide smile and the booking sheet that ran the late 2010s. A Los Angeles kid signed to IMG out of high school, she walked Desigual at New York Fashion Week in February 2014 and never came off the calendar.

Arc

She debuted at Desigual in early 2014, then took the Tom Ford Eyewear campaign that July alongside Patrick Schwarzenegger. Victoria’s Secret in December 2015 with the wings, again in 2016. The American Vogue cover came in August 2017 with Zayn Malik. Then the volume. Versace, Marc Jacobs, Tommy Hilfiger, Fendi, Chanel. Two daughters and Vogue covers from Italia to Arabia. She launched the cashmere line Guest in Residence in 2022 and stays one of the most-booked models on the runway calendar. The British Fashion Council named her International Model of the Year in 2016.

Why she’s in the library

A face the model reads cleanly. Wide-set eyes, soft jaw, a smile the lens has tracked since New York 2014. Holds across runway light, magazine cover, paparazzi flash. The geometry the algorithm anchors to without slipping.
