Italian handbag designer Carla Braccialini has her job in her genes: her family’s business was founded back in 1954. Today the company has her to thank for its reputation as a purveyor of women’s handbags with a twist. Braccialini produces for big-name fashion labels like Vivienne Westwood, and her new, limited-edition bag based on a design by Leonardo da Vinci goes on sale this month.
