The issue here isn’t that the clothing industry resized a 4 to an 8 as she suggests, but rather vanity sizing and expanding waistlines has pushed some manufacturers to resize the other way.
An 8 from 30 years ago is a 4 today because a woman can go to that store and say “wow I fit into a 4!” and it makes her feel good about herself and she’ll purchase those jeans rather than her true size from somewhere else. The focus should still be on the fact that we make it so women view themselves based on how they compare to unrealistic standards of beauty being thrown at them, which is why she’d feel great about that size 4 in the first place.
Vanity sizing has completely screwed up the way women shop for clothes making it nearly impossible to buy anything without trying it on and the whole industry needs to convert to actual waist & length measurements the way mens pants are sold. A 32 is a 32 is a 32…it’s not a 4 at Old Navy and an 8 at Uniqlo.
I worked in retail for 10 years – obviously I realize vanity sizing exists for men as well. But as someone who has a closet pretty equally split between men’s and women’s fashion and as someone who has been roughly the same size since junior year of college, I can tell you that women’s vanity sizing is on a whole ‘nother level and has gotten considerably worse over the past decade.
