These days, it’s rude to say that someone is fat or large, so the fashion industry calls them “plus sized.”
Which begs the question: Is there a “minus sized”? And what exactly is a size smaller than zero?
I’ve known some size zero models, and any thinner than that, they need to buy something to eat, not more clothes. Or heroin.
Do identical twins or triplets wear “multiplication sized” clothes?
What about a “divided sized”? Does that cover amputees?
Does your imaginary girlfriend wear “square root of minus one sized”?
It’s all a moot point. Most models suck at math.
