How much do we love it when Robert Duffy takes over the @MarcJacobsInt’s twitter account? He answers all our questions and gives us all such amazing insight into the fashion house. Joining Duffy on Twitter is Burberry’s Christopher Bailey who started tweeting from @Burberry yesterday in the lead up to his Burberry Prorsum show at London Fashion Week. So far he’s taken us to the BBC studios, seen him tweet to Victoria Beckham and found out what music he’s listening to as he puts the finishing touch to Burberry’s Spring Summer 2011 collection, set to be unveiled on Tuesday September 21.
