Okay, I was a teenager in the '70s. Some of this is very familiar to me because I saw it every night on TV. And if you pick up any Archie comic from that era, you'll see the male characters wearing print shirts in the daytime and shirts with frills for evening wear.
But holy crap, I never saw ANY man in that decade or any other wear a knitted/crocheted poncho. The only men I have ever seen wear a poncho at all is Clint Eastwood in his spaghetti westerns And those were woven, not knitted. (I seem to recall that Luke wore a poncho in a couple of the scenes in Star Wars, too)
BTW, those "gender-bending" sleep shirts? They're not "gender-bending" at all. Men wore stuff like that to bed for centuries. Men's pajamas are actually a fairly modern thing.
Boy are some of these articles ever going to look awkward when leisure suits and flared pants come circling back around.
(Those plaid slacks the one guy is sporting in the "Slack Power" ad are really just mod fashion. People wear stuff like that today. Notice also the prevalence of knitted clothing, which is coming back in a big way -- mostly confined so far to toques and shawls and sweaters, to be sure, but give it another few years and I wouldn't be surprised to see knitted tunics and ponchos. Indeed perhaps we have
already crossed that threshold.)
Obviously those TMP uniforms were influenced by the ascendancy of one-piece leisure suits, of course.
Some of those knitted tops/tunics were popular with women and teenage girls. Never saw men or boys in them. Not once. The outfit in #2, for example, is one that a woman would wear with no problem. On a man it just looks weird.
Most of those abominations can be traced back to one culprit: polyester.
There's nothing wrong with polyester, as long as what it's made into doesn't look like something weird. Mind you, my definition of "weird" is a bit flexible, considering that I'm perfectly comfortable with walking down the main street in my city wearing an outfit from the 10th century and see nothing wrong with men wearing kilts or anything else from the medieval era. People who spend any significant amount of time in the Society for Creative Anachronism quickly become accustomed to wearing their garb in public, especially if engaged in public demos, as our branch often did.
Some of those Elizabethan getups were bizarre, though.
The irony is I grew up in the 70's and didn't know one person who dressed like that. It was always something you only saw on TV.
Some of those outfits are straight out of '70s cop shows, not to mention some of the science fiction shows.
