EATER OF WORLDS & CHLDREN
For DeNiro (Jimmy), he wears a sport coat and tie most of the time. Also wears the sport coat with no tie quite a bit. The scene where he is choking the cleaner, is one of the few I can think of when he is dressed completely casual.
He's also completely casual in the 1st pic you posted with the leather jacket.
I like those looks for Tommy but I'm gonna throw the flick on tonight and skim around for an outfit refresher.
