I think its not necessarly a mafioso uniform but more of how alot of italians dress. also, how theyre broughten up. alot of these guys there fathers uncles cousins etc are mob guys and brought up dressing like that. merlino that is also true ill see alot of guys in the middle of the summer with a full jumpsuit on. but how they were broughten up and culturaly i think has something big to do with it all
