Just last week, Marc Jacobs president and recent Twitter convert Robert Duffy tweeted a request for set ideas for the label's fall show. That apparently spurred Jacobs himself into action, and he more than rose to the challenge: As the show began, spotlights picked out the designer and Duffy tearing the brown construction paper from a wood frame structure at the back of the Armory. The paper duly removed, all 56 models were revealed, standing in formation on the raised platform and staring back at the audience.
