It's funny to watch old shows where they (try) to make fun of fashion of the previous decades. Sure, it worked at the time, but watching those same shows now is nothing but "making fun" of earlier styles. Of course those shows exaggerated those past styles to make it more apparent and humorous whereas they were considered trend setters for their own time.
But this requires those shows to originally be aired long enough time ago. Too recent, and it still feels moden enough not to make the distinction between current and old fashion. Or is it just that it hasn't really changed that much in the past few decades. Have we perfected the style, or is everything just become too boring when brands try to play it safe and nobody really wants to stand out.
Looking back at the last century and there was a distinct styles for each decade. You could easily tell in what time something was set just by looking how people were dressed up. Not so easy anymore on this century.
