If you're looking to invest in a worthy Fall accessory, look no further than the duffle bag. As this trio of style-setting blondes proves, the arm candy exudes both fashion and function — and we love when those worlds collide in one lust-worthy creation. Kirsten Dunst and Kate Moss each opt for luxe, leather versions from Louis Vuitton, in their own respectively sophisticated hues, while Sienna Miller selects a covetable carryall from Burberry Prorsum's 2012 Resort. Each signals a polished finish for day-to-day basics, and seems particularly perfect in rich leather and deep colors for Fall. To channel the same classic-cum-cool style with your own luxe duffle, just shop our editor's picks.
