However it's also way off the mark because it doesn't treat the professional dress from a technologist standpoint but rather a socio-cultural one and doesn't go into the history of the shirt and tie (notice I didn't say suit and tie) as a communication medium

There's enough information here for a whole volume but whatever it's worth humans require signals to communicate and in the absence of something definite they'll use anything at hand

The traditional professional dress deals with social communication concerns we're no longer even aware of let alone leveraging to advantage and it's a pity to watch a whole generation of would-be professionals on a level the world has never seen in its billion year history lose the thread as it were and bring their shabby hand me downs to the arena when they could stand on the side of tradition and button up like their ancestors in the arts and sciences did for centuries before them
