I started commuting into NYC about 35 years ago. Then and today, my very early 5:15 am train was largely populated by either the construction trades or Wall Street types. In the decades past the construction guys were all in clean work clothes and were well groomed (no 2-day stubble). Finance folks in suites, usually navy or dark grey with white or pale blue shirts and subtle ties. Shoes were immaculately polished (most office buildings had a shoeshine station). Today many of both groups look like they just rolled out of bed (or the gutter after a hard night). Many are so slovenly that I really wonder how they leave their homes that way. I wouldn't take my garbage can to the street looking like that. This is not everyone, the majority still look sharp (except for their shaving habits) and take pride in their appearance even though styles have certainly changed with suites in the clear minority and "business casual" the uniform of the day.
