Part of the explosion of Michael Kors' fashion line and brand has been the fact that for the past 10 seasons he has been sitting as a guest judge on project Runway. There is nothing like hours of free publicity on national television to make your brand explode and sales go higher. For the 11th season though, Michael didn't have the time to shoot and is being replaced by Zac Posen. Zac has been a guest judge before but this will be the first time he is there for an entire season. Michael will be back for the season finale, but I'm wondering if Zac does really well in the ratings if Michael might be shown the door. He can get on my nerves after about three or four episodes.
