Marc Jacobs And Robert Duffy Get Ready For Fashion Week On Twitter (PHOTOS)

With New York Fashion Week starting today, Marc Jacobs President Robert Duffy hasn't slowed down on Twitter at all, posting behind-the-scenes pics of what's going on in the world of Marc. He shared this photo of "Me and Marc not looking so good after working for 20 straight! And all nite!" guys look great!

Last year, Duffy used his favorite micro-blogging site to put up images of Marc prepping for Fashion Week in sandals and socks. Most recently, Duffy has taken to Twitter to discuss launching a plus-size line.
