People change, not just since the 90s. Just look an old movie, like Dirty Harry, or look pictures from athletes in the 70s, 80s. It does not so much plays a role, as long you try in a store. But online it sucks very much right now. Recently I ordered a pair of pants, and it was something like 3 sizes smaller, than the same model in another color. I'm not sure, if online stores and factorys think people would not return the item and just order a size larger or smaller again. I think thats also a point where the EU should push, a true size with cm.
