Ha ha! These are the fashion mag 70s Dave. The men on the street were wearing small collar button down shirts, high waisted pants, platform shoes and tank tops. These are the arty fashion mag styles from that era. Both funny to look back on though.
I was around in the 70s and never saw any of those, though the moustaches were a thing.
But I think what's really awkward about looking at the ads is the notion that males had fashion at all. The very idea is now unfashionable. It was (like much of the 70s) the commodification of individualist 60s styles.
I was 7 when a brother left home to pursue his career, he had always been short back and sides, white shirt etc.
Came back a few months later to visit, shoulder length hair, purple shirt (sort of flowery) mum and didn't recognise him
Just as well they took me with them when they went to meet him off the train!
That was 1970 :-)
