I kinda agree with you and often wonder at the osmotic effect of our perception of what is 'fashionable'
I can think of a few styles/items that I've looked at in a perplexed like horror over the years which has gradually changed by exposure to them. Thus is the ever changing cycle of fashion and what is and isn't 'acceptable' and it's been like this before Beau Brummell was a twinkle in his daddy's eye.
It's all driven by capitalism and consumerism as well as status which has been magnified in our world of social media, fast fashion and production methods these days.
Also, the changing way that we're expected to act and behave as people at different ages too. My maternal grandmother was born in the last year of Queen Victoria's reign and the day she turned 60 she got rid of anything deemed colourful or 'unsuitable' in her wardrobe and donned a uniform of dark dresses with the occasional small polka dot or print.
The same way that 'elderly' women in my youth adopted the ubiquitous 'old lady' hairstyle, although when I'm in my 70s it'll probably change again.
The societal shift that means women are having babies later, working, health outcomes etc has blurred the strata of what was once perceived as 'old' so we're more aware and influenced by fashion.
And kids in their 20s will always be at the forefront of what we think is daft fashion because that's what kids do, even with any nefarious consumerism powers driving them.
Like I said with the wearing above ankle socks with trainers, I'm open enough to admit vanity plus the good natured influence of my teenage kids but I'm also well aware of the fickleness of it all?
I must reiterate that the teeny tiny sock wearing man would've put anyone off. He also licked his knife at dinner and looked like he'd had his toes and soles coloured like he was a hastily cast Mr Tumnus in an am dram production of The Lion, The Witch and The Wardrobe so he certainly wasn't getting to sample my Turkish delights.
