Ad agency Leo Burnett put this poster up in its offices this week, announcing a new company dress code. Even the creatives would have to wear collared shirts and cotton trousers! And the ladies! It's obviously a big ol' joke designed to help Leo Burnett seem "cool" and "with it" even though they are a huge and ancient company. But it freaked out all the ad bloggers! Ad Age's Adages blog points and laughs at those duped. Meanwhile, ad agency creatives are still allowed to not dress like assholes despite being assholes. [Adages]
