At least for popular brands of jeans, the "inch" measurements have succumbed to the exact same nonsense: https://www.esquire.com/style/mens-fashion/a8386/pants-size-...
"But vanity waist sizing is so entrenched, it couldn't possibly be changed overnight, at least not without a government mandate. The only solution seems to be a gradual, year-by-year shaving of quarter-inch by quarter-inch until, in 2021, men's pants finally correspond with the label numbers — conveniently just in time for the New World Order's switch to mandatory full jumpsuits."
That sounds terrible, but it could still be an improvement over 2020.
