In the last year, Hailey Bieber has become one of the most-snapped stars and our personal fashion muse for relatable outfits (thanks to her casual-cool Cali-girl roots). As we're starting to think about what to pack for festival season, it's a no-brainer that we're turning to Bieber for outfit inspiration. We asked the model all about her essentials, which include stylish yet practical pieces from Levi's® like her favorite 501® denim shorts (she is the first official face of the jean after all). Curious to see what else makes the cut?
