Reminds me of a cafe in Oxford in probably 1976.
During a spell of very hot weather the female owner banned topless men. Her argument was that women weren't allowed to be topless there by public opinion or law - so men shouldn't be allowed either.
I once threw a Vicars & Tarts party (definitely no longer PC) for people from the office. It was interesting the amount of licence the women took in their outfits - especially those who had been regarded as rather prim and proper.
On an earlier occasion I had a flat warming party. The next door neighbour was renowned as being a prim battle-axe who always complained about younger residents' behaviour - but I invited her out of courtesy. The flat had just been renovated - and on the carpet was one of the popular goat skin rugs. To the amazement of the assembled company the neighbour made a bee-line for it - and gave a very sultry impression of Eartha Kitt singing "Old Fashioned Millionaire".
An invitation to a friend's birthday fancy dress party was accompanied by a warning that one of the neighbours pulled mens' trousers down after she had had a few drinks. I went in a grass skirt with "warpaint" on my body. At some point someone jokingly asked what make were my briefs - so I took them off - having a G-string under them. The woman was then encouraged by the company to take my G-string off. It became obvious that pissed as she was - the public challenge and my neutral stance - voided the kick she would normally have sought. .
