It is probably right to say that most companies have some sort of unwritten corporate dress code, I can remember back in the 80's that Duracell, then an up and coming company, seemed to attract men who wore white shirts, red ties and blue suits!
But how far should a company go in directing dress code to employees? It would appear that the Swiss bankers UBS went a little too far in their style guide (see article here), for example;
– Breath – no garlic or onions
– Hair – men to cut monthly
– Makeup – women how to apply it
– Underwear – skin coloured (how are they going to know???!!!)
They admitted they went a little too far perhaps and are revising it.
