The people who actually complain about such things never watch films that old?

And fedoras never go out of style. ;)

Yeah,I have two fedoras that i wear all the time. Also the standard gray and black suits most people wear in those older movies are pretty close to what office workers wear today,the cut of the suits is really the only thing that has change. Whereas the colours and patterns,and materials that were used in the clothes from the decades you have mentioned are wildly different from what is worn today so it is easier to tell what decade the film is made in from the clothes. Generally speaking it's things like the cars and the lighting that give away the decade a film from the 30s-50s is made in,and it's the clothes that give away what decade a movie from the 60s-90s is made in so that contributes a lot to those films seeming more dated then others if you ask me.
