Peter Eggers (Johan Gustav Dåådh) and Joel Spira (Simon Freund) both sport a highly anachronistic 3-day stubble throughout, whilst the others are thoroughly shaved. They maintain this look, every day even if it would have been hard to look so unkempt, as they're beards do not grow.
Some other things as depicting most poor people as dirty even at nighttime is absolutely wrong. Most people bathed weekly, and all washed daily.
People in dirty lines of work would bathe daily after work.
