Shave, dammit
On seemingly every program I see men wearing a three day stubble. Apparently, this is fashionable these days. However, it is not acceptable in most offices today and was certainly not fashionable in the 1980's.
Nobody would be going out clubbing without a shave (unless they wore a beard). They would have been considered sloppy. A police detective would be dressed down if he was not shaved. Even if coming off an all night assignment, an officer or detective would shave before reporting.
While I don't care for the fashion statement, the least producers could do is keep it out of periods where it certainly never belonged.
