Balenciaga's Souvenir leather bag debuted during the Spring/Summer 2018 collection. It can be worn at the waist as a fanny pack. It can also be worn crossbody style, as seen on the Balenciaga runway and on supermodel Rosie Huntington Whitely. Gold and enamel charms dangle from the gold leather and chain strap. They pay homage to Paris, the location of the fashion house's headquarters.
