So the white shorts are a size 10 made about 2 years ago and the black shorts are a 10 made this year both from American Eagle. Now the whites are a little loose on me and the blacks are bran new and probably a bit tight because they need to stretch a little. That’s not my point though my point is that the 10 now a days is what an 8 was about 2 years ago so if you weigh the same and have to go up a size or two it’s because designers are ass holes!!!! That size is just a number so yo can find a brand you like and not have to try on a million pairs of bottoms when you need a new pair. Own that fucking number!!! It doesn’t own you.
I’ve been experiencing this for years. I own an H&M parka that I bought 8 years ago when I was 17 and I still wear it. The same size today is probably in the girls’ section.
