The sisters have definitely landed full-time roles as fashion authorities. Surely, growing up in Lionel Richie's household couldn't have hurt. When she was 14, Sofia told Teen Vogue that she'd either find herself in her father's studio or in her family's wardrobes — neither of which were ever off-limits. "Sometimes I go over to [Nicole Richie's] house when she's out of town, and I steal stuff — the nanny lets me in," she said, explaining how she borrowed Balenciaga bags and accessories from Nicole's closet.

She also "borrowed" from her mother, designer Diane Alexander, telling Grazia,"I actually take a lot of stuff from my mum. She has really cool old pieces that she used to wear — she has separate closets for the clothes she actually wears and then all her old stuff. She has a full-blown vintage closet in the house, it's so cool." 

And while Sofia's style seemingly embraces every aesthetic, she admitted to Teen Vogue, "Nicole is definitely my style icon, and she's the best person to go shopping with." At the time, she even foreshadowed their 2021 collab, saying, "When I'm older, if I'm successful at everything, I want to come out with a clothing line." 14-year-old Sofia would definitely be proud!
