My wife is a thin Asian. 5'3", 39-years-old, multiple kids, and consistently at or just under 105 lbs outside of pregnancies. (Shockingly, despite our totally different genetics, neither of us are overweight. Maybe, just maybe it has to do with eating reasonable portions of healthy, home cooked food for the vast majority of our meals?)
She used to buy a lot of Old Navy S or XS clothing. Everything from the last several years would be XS only. Now XS is too big.
My wife is not shrinking. My wife is not growing. She's been as consistently the same size as any human in their 30s could be.
It's only anecdotal evidence, but Old Navy, like many, many other stores, seems to have vanity sized to the point that my very human wife can no longer buy clothes there.
Yeah, it's cute when you're in your late twenties or early thirties and you're buying things in the juniors because the women's section is too big for you...but it's insulting that my wife can no longer find clothes her size made for women her age because she's not fat enough.
Rewind to the 1950s and not only is her height totally in the normal range, but so is her weight.
Today? She's considered an outlier that's ignored so we can pander to fat fucks who don't want to buy properly labeled sizes.
