Jewish

Black clothes are known to Jews as a symbolic expression divrai yirah shomayim – this means “fearing heaven”.

To some Jewish people,  life is serious and they are always conscious of their relationship to G’d. Black is worn to avoid frivolity and to also place distance between the wearer and everyone else.

Orthodox Jews wear a prayer belt called a g*rtel in German or Yiddish. This belt is to indicate that the wearer separates his upper body from his lower body as the head is the location of all that is inspired while our bottom serves lesser purposes.
