Marc Jacobs is beginning his personal elongation campaign. With each passing season he appears remarkably fitter and skinnier. This week Jacobs even looks like he could have swapped clothes with his good friend and male muse Pharrell Williams, who will introduce his highly anticipated LV Blason collection of fine jewelry, designed with Camille Miceli next week. But for the moment, the emphasis was on enviable bags and the introduction of the brand new Damier Graphite sack that Williams played around with backstage.
