The day white socks became uncool
One day back in the 1960s it was possible to wear white socks to school and go about one's business unmolested by the fashion police.
But then, on the next day, word got around that boys wearing white socks were unfit for decent society and should be hounded from our midst.
Not sure who decided this. But I suspect it had something to with either troll dolls or madras and paisley shirts.
