Bella, who's no stranger to navigating tricky trends, wore side-slit Givenchy denim with a cutout top from I.AM.GIA, Salomon sneakers, and a vintage Goyard bag. She finished her look with jewels from Mercii', Beepy Bella, Bea Bongiasca, and Emi Jay, adding Gucci sunglasses as the final touch while out in Paris.
