The gambino's and genovese still dress up
Sure, some of the older guys still take pride in how they dress. But the Genovese are the wrong example. As a rule, they NEVER flaunted their appearance like the other families. Fat Tony used to wear fucking overalls on 116th Street
.
There are exceptions, of course. But to this day the Westside will reprimand their guys for living over their heads and putting on a show with luxury cars and fancy clothes. But they dress down for a reason, to deflect attention from themselves. When guys in the other families dress like slobs, it's not a charade. They're just fucking slobs.
