Clothing makers already do this. It’s called vanity sizing. What used to be a “small” shirt or dress is a lot larger than it was a few decades ago.
Even men’s pants, which pretend to list the waist size in inches, are lying to you. My actual waist is about 36 inches. I wear jeans that claim to be 34 inches and are loose on me.
More detail:
“In 1958, for example, a size 8 corresponded with a bust of 31 inches, a waist of 23.5 inches and a hip girth of 32.5 inches. In ASTM’s 2008 standards, a size 8 had increased by five to six inches in each of those three measurements, becoming the rough equivalent of a size 14 or 16 in 1958. We can see size inflation happening over shorter time spans as well; a size 2 in the 2011 ASTM standard falls between a 1995 standard size 4 and 6.”
