It makes sense for work environments to have some sort of policy for how people dress. My line of work makes anything remotely revealing inappropriate - when it is teaching and hospital work. I also care a lot about being taken seriously and have found in professional environments that men don't stay in "idea space" with me as much as with other men. They end up talking about their wives and girlfriends and relational ideas. It is strange to me, but that is what happens, and I smile and nod, but don't have anything to say about that. I also have gotten hit on completely without provocation at conferences even when dressed very conservatively. It is just too hard to be seen without gender reference and dressing sexy could only exacerbate that issue. I want to interact in idea space professionally and so would not wear anything to distract anyone away from that.
