LOUIS VUITTON Twist Pm Black Epi. This twist pm chain bag in grained epi leather is accented with the now-iconic lv twist lock, a sculptural signature in silvery polished metal. Compact but surprisingly roomy thanks to the cleverly designed “wave” base, this beautifully crafted piece is a fashionable day-to-evening companion. The sliding chain strap can be doubled for shoulder carry or lengthened for cross-body wear.
