Inspired by the functionality found in travel bags, Hedi Slimane created the Sac de Jour in 2013 with the hopes it would be an all-around bag suitable for every and any occasion. Continuing to reimagine its most iconic tote, Saint Laurent's dreams up the latest iteration of its signature Sac de Jour bag – and this time, it comes in nano proportions. Dreamt up from croc-embossed leather, this boxy silhouette boasts a spacious interior to hold your phone and lipstick, then is fitted with a padlock keyring to keep your belongings safe. Carry yours from its top handle, or slip it over your body with the detachable strap when needing to go hands-free.
