If only the "without great expense" part was achievable outside of fiction.
Well to do women had the practice of wearing a dress a couple of times and donating it, so a thrift store habitue could be well-dressed on a budget if a year or two out of fashion.
There are a few places where one can find men's bespoke gear but it tends to be well used, and I am not about to try removing a sleeve at the shoulder so I can show the right amount of cuff.
You definitely may find a perfect piece at a thrift though it's not easy in California.
Back to the original thread: does anyone have some sartorial Dostoevesky? I seem to recall that Rashkolnikov had some threadbare duds. Someone once said (I think it was George Steiner) that you're either a Tolstoyian or Dosteoveskian....
