How this Gen Z founder got the coolest girls in the world to wear her jeans, from Taylor Swift to Hailey Bieber — and built a multi-million dollar denim brand

• Emily Bonvicini started selling vintage Levi cutoffs in 2016 while still in high school.
• Her brand, EB Denim, has since been worn by Kylie Jenner, Gigi Hadid, and Emily Ratajkowski.
• The brand, which is set to do $3 million in revenue in 2024, leaned into influencer marketing.

Emily Bonvicini, the 25-year-old founder of EB Denim, was at a New York Fashion Week after-party last September, drunk, at 4 a.m., when she got a tip from Taylor Swift's stylist that the pop star was planning to wear one of her pieces.

"Oh, that's cool," Bonvicini told Business Insider she thought to herself at the time. "And then I wake up in the morning, and it's like, cha-ching, cha-ching, cha-ching, cha-ching."
