The 1970s was all about extremes. Fashion was both shockingly tight and incredibly loose, often within the same outfit. It was more than a trend—it was a vibe. Just like fashion, popular culture had its own rebellious streak. Films were grittier than ever with scenes that would cause a riot in theaters today (if people actually went to theaters). At the same time, disco might have "sucked" but it ruled the music scene and became the soundtrack to iconic "only in the '70s" movies like Saturday Night Fever.
