On your first point, I agree - men might be in their "Sunday best." My point is, 1) everyone had a Sunday best, and it was pretty good. 2) They wore it fairly often, not just weddings and funerals, like today.
The photo in Manhattan in 1929 with which i started this thread was undoubtedly taken during the week- the men in the photo are
observing a "noise" study being conducted by sientific/engineering professionals, who are by our SF standards very well- dressed.
Regarding cost approximations over the decades, a simplier examplle may be seen in men's haircuts. Because haircutting has not benefitted
by any signficant improvements in productivity for probably centuries, the cost of a haircut rises at least with the rate of inflation. It may also be
influenced by the availability of barbers, which is, in turn, a function of alternate occupations open to those who might in an earlier era have chosen
the barbering trade instead of IT or x-Ray technology.
